Question - how do you gentlemen handle holidays and birthdays? I don't want to celebrate anything with this woman but also understand there's kids and they have feelings too.

Context: wife cheated with a co-worker last year. We separated in January and she moved out in April. Kids are 20, 18, 13.

She moved to an apartment about 30 minutes away and visits the kids at my house a couple times a week.

My oldest daughter turns 20 on Wednesday. My STBXW suggested going out to dinner.

I'm trying to interact with her as little as possible but she keeps trying to act like we're a family.
