Reply To: Is it alright if I don’t say anything?

You’re not obligated to share or withhold information. If I were in your situation, I would be honest if asked directly “hey, why isn’t Tanya talking to me anymore?”, but otherwise casually avoid the topic. If Tanya asked you to not say anything to Denise, you can simply say “you will have to ask Tanya about that.”

This is not your burden to bare. You are the only one in control of your relationships – you can’t control who other people like.
