I need opinions

Vanessa

My sister in laws boyfriend sexually harassed me on a family trip two weeks ago. Since then my anxiety has been through the roof. Now I have a family dinner tomorrow where he will be there. It’s for my mother in laws birthday(who passed away 11 years ago).

Is it rude if I just don’t go? Or should I suffer through all the anxiety to support my husband?

He says everyone in the family understands if I don’t go.
