Well, there's always avoidance and ignoring them, but it kind of sounds like that doesn't work. My aunt is an alcoholic and wen they are drunk, telling them something they don't wanna hear is pointless. Perhaps if u catch them wen they aren't belligerent, u can just tell them that ur sorry but ur going through some things and u really need some solitude? Idk. If u could tell them a toned down version of the truth its best burning imagine that might cause them to become more difficult. Maybe u can make up.a reason for not participating that's beyond ur control. Tell them ur husband, employer etc is giving u a hard time so u can't participate because it will cause marital tension/ risk u getting fired? I'm not sure this has been terribly helpful but I hope so. With my aunt I finally had to tell her "I don't like u and I want nothing to do with you. If u call I won't answer, if u home by my house I won't answer the door. I have children and i don't want them seeing an adult over here falling down drunk and belligerent, so please respect my boundaries and privacy and leave me alone." She wld continue drunk dialing me and then come by wen I didn't answer but after two times of knocking on my door and peeking in my windows for a half hour wen she cld hear ppl inside, she FINALLY stopped. Hope to help. Good luck.
