Awkward Situation Got Much Worse (part 4 )

[Tate]

I get it...the question is how can I force either one to not show up without telling the whole family what is going on?

Example: My other sister invites my BIL and wife to Thanksgiving dinner. I can tell my W not to go, but sge will still show up. Then what...make a scene? See the problem?...no way to enforce no contact without telling everyone in both families...

Othets have said that I should refuse to show up then...and never see my family?
