My mother is convinced my father (her ex-hus. of 25 yrs) is gay, and she's very upset that he's getting remarried. I'm going to visit her early next month, and she wants to talk to me (again) about why "he's gay" and why my children and I shouldn't attend the wedding. I don't want to have this conversation, or any with her about my father. How should I handle this? She gets nasty when things don't go her way. I was planning on staying in her house for the visit, but I don't have to.
