Yeahhh. You didn’t *stumble* onto a woman’s Instagram profile and it just happened to be this guy’s girlfriend/fiance. You were online doing a deep dive looking for… something. And now you’ve figured out that your “boyfriend” is a liar and a cheater.
It sucks and I’m sorry. I can even understand the desire to bury your head in the sand — denial was my initial reaction to getting cheated on years ago and I spent several days trying to convince myself that the obvious couldn’t be true. (Spoiler: It was!) But it’s been at least a month since you figured this out, right? The lies have continued, you’re not feeling any better or more secure. Time to believe what you know to be true. Time to believe that you deserve better and walk away. There are other, better men out there.
