“My In-Laws Invited My Dangerous Sister-in-Law to Christmas”

I’m writing because my husband and I are struggling with the fallout of maintaining boundaries we set years ago with his sister, “Jane.”

For context, Jane has a long history of violent, manipulative, and unsafe behavior. Because of this, we made a clear decision several years ago: We will not be around her and we will not expose our children to her. This boundary wasn’t impulsive or emotional; it was made after repeated incidents and serious concerns for safety. We have never asked anyone else to cut her off — only to respect that we won’t attend events where she is present.

The problem is that much of the family continues to excuse or minimize her behavior. Whenever she offers a brief apology or appears temporarily stable, our boundaries are treated as unreasonable or punitive. We are pressured to “move on,” even though nothing meaningful has changed. As a result, we are often excluded from family gatherings or forced to choose between our boundaries and participating in traditions. This has become especially painful as our children get older and notice when we aren’t there.

We’ve now been told that the entire family will be spending Christmas together with Jane. The message to us is simple: either break our boundary or don’t come. There is no compromise and no acknowledgment that this boundary has existed for years. We feel heartbroken and exhausted. We want our children to have relationships with extended family and to participate in holidays and traditions. But we also believe it’s our responsibility to keep them safe and to model healthy boundaries — even when that means being misunderstood.

So my question is this: Are we being too rigid by holding firm to a boundary we set long ago for safety reasons? And how do we cope with the guilt and family pressure when maintaining that boundary means missing out on important moments? — A Tired Parent Trying to Do the Right Thing

An emotional boundary is a tool for managing relationships in a way that preserves a person’s mental health and physical safety, and prioritizing your children’s safety is ALWAYS an important boundary. If Jane still presents a safety risk – and nothing you’ve shared here suggests she has received help, made amends, and exhibits changed behavior – you are right to protect your children from her. Being right doesn’t mean you’re spared from negative feelings and consequences. It sucks to be left out, to feel misunderstood, to have your children question why they aren’t included in family holiday gatherings. But it’s your job as the boundary-setter to adjust your behavior when a boundary isn’t respected, and it’s your job as a parent to protect your children’s safety (even more than creating the illusion of happy, holiday family coziness).

So, how do you cope with the guilt and the family pressure? Assuming you and your husband are on the same page – and if you aren’t, that’s a whole separate issue – stay firm, and create new traditions. Instead of caving to pressure, say, “We have been clear that we don’t feel safe around Jane and if she’s invited, we won’t attend. However, we’d like to [insert new family tradition here] with you. Would you be available on [insert a few dates and times as options]?” You can suggest a family cookie decorating session at your place, driving around looking at Christmas lights, a meal at your place or a favorite restaurant, a gift exchange, decorating the tree together, or any other holiday-themed activity that sounds fun and appeals to multiple generations. It’s never too late to start new traditions, and when you are the one to organize them, you get to be in charge of the guest list. It also takes the pressure off you to conform to a pre-existing tradition with a guest list you have no control over, and it puts the pressure on others to accept your invitation.

Ultimately, boundaries are really about the behavior of the person setting them. You can’t control what other people do and say, but you can control your response. When a boundary is tested, it’s natural to question it, but I urge you to remain firm and compassionate – both with yourself and with your in-laws who are dealing with a family member whose struggles likely affect everyone to varying degrees. They’re probably doing the best they can with the tools they have, and you are responding the best you can with your main tool being a boundary that has, thus far, kept you and your kids safe.

  1. I cent help but feel like more information is needed to decide if the boundary makes sense.
    In what ways was her behavior a safety issue? What does the writer mean by violent and manipulative? I know what I define those things as and I would absolutely support maintaining the boundary if they are as described, but I find it interesting that no examples of behavior have been given. If that is to protect anonymity that is one thing, if it is because there aren’t any great examples there could be more to it.

    1. Can’t not cent… don’t have my glasses on and it autocorrected wrong and now I can’t edit 🙂

  2. There is so much stridency and judging going on about Jane’s past behaviors. When the letter writer’s children were younger, it probably made sense to keep them away from Jane and the drama/risk she could pose. But the rest of the family seems not to feel the same level of risk and this had been going on for years. Is Jane still acting out and presenting an emotional and safety risk to others? Can the parents minimize exposure to Jane and observe her with fresh eyes, while still attending family gatherings? This couple seems so set in their judgements and punishments and ultimatums that they seem to mostly be harming themselves and their relationship with the rest of the family. They can talk to their children about their concerns about Aunt Jane and leave early if Jane gets out of hand. Time to reassess.

    1. My sister in law is a violent criminal who is bipolar. Leopards never change their spots. The rest of the family enables her behavior. When someone demonstrates repeatedly who and what they are, believe them. She will never change. She would be stupid to change, because she likes behaving the way she does.

  3. Please ask yourself if one of your children has struggles will you exclude them from family gatherings? This is their child and they love her.
    It is healthy to reassess boundaries over years. For example, how does SIL seem to be doing now, does your husband want a closer relationship, can you go for two hours to see everyone and see if you feel better about it?
    Are your children old enough to be able to understand an explanation on their aunt’s behavior? Keep the boundary if you are truly afraid. Best of luck

  4. No examples = examples don’t match the description. So yes, you are being too rigid.

  5. Still Trying says:

    You set the boundary. You don’t also get to tell everyone else that boundary means you’re offended when they respect your willingness to miss events because of your decision to impose a boundary. You don’t get to tell them how they live within your boundaries. I presume you’re still “welcome” but it is you and your husband that decided you won’t be going. IF you feel that you set a boundary hastily and are finding YOU want to adjust that boundary because the impact is more dramatic than the potential damage, well that’s a different story.

    Why don’t you spend the holidays with your own family? Problem solved. You have two families, right? You can meet your husband’s family on your own terms separately from Jane at an other time, and get your children to enjoy a family party at your own parents or with them. Don’t focus on being excluded, don’t focus on the drama. You indeed can’t control what your in-laws are doing or deciding. But you can make your own decision given that you do have a choice: just visit or invite your own folk, or friends or plan an other kind of holidays.

  7. I agree with Wendys ending to be compassionate to your in laws. There’s nothing stopping you making arrangements with them to meet up another time or have a trip together without Jane. It seems like the boundary is to punish anybody in close proximity to her at present.

    It’s not unreasonable to have your boundaries and I’m sure the decision wasn’t taken lightly and the right thing to do at the time for your safety and wellbeing.
    My family has a similar issue and it’s been incredibly difficult for everyone to manage, so forgive me for projecting a bit. One side of my family won’t have anything to do with my sibling as when manic she behaves terribly and has no remorse. Even when well and just normal again, she doesn’t acknowledge the harm she has caused without trying to justify her behaviour as part of an apology, or seem to remember what happened clearly.

    But if my parents and myself cut her off, then she will have no-one that cares and it’s this that makes my parents side with her, even after everything. The divide has absolutely ruined the last 10 years of mums life and meant she doesn’t want to celebrate events or even have a funeral when the time comes due to said boundaries. There have been times I wished my sister had a life limiting illness or something people are more compassionate and forgiving about, which is a terrible thing to feel.
    At least you have your own family to be with and make memories and traditions. Hopefully your children won’t develop a life destroying mental illness, personality disorder or addiction in the future as it’s truly terrible to be part of.

  8. Setting boundaries is tough and you have to be mentally tough to carry them out. Wendy’s suggestion of creating other events is the best course of action.

    I have a sister whom I do not speak with. She is mentally unstable and toxic. But only to me. She was extremely jealous of another sister being born. We have not spoken for 36 years. My dad hates that we don’t speak and we are both always invited to family events. It always made me mad that my siblings and my parents did not side with me and allowed my sister to be rude and offensive to me. And expected me to just get over it. There were times that I also thought about cutting them from my life as well, for my mental health. But it’s difficult and I understood that they were weak and were not strong enough to draw boundaries like I was.

    My point being if you believe in what you are fighting for then you have to dig in. Setting boundaries is never easy. You have to live with your choices and know you are doing the right thing for you.
