So, as you know my FI's cousin has been quite an asshat. I have tried to avoid him. I have tried to let his comments go into one ear and at the other, but his comments, and his craziness have slowly been eating away at me. He hasn't apologized for his god awful comments he made about me and our future child. A week ago, I put on my big girl panties and extended an olive branch by offering to host his future wife a bridal shower (none of the other family members have offered due to their reservations about their relationship). I called the cousin, and spoke with him for a few minutes, he was very vague about his response, so I said he could get back to me when it was more convenient. A few minutes after getting off the phone, I receive a snarky text saying that I should mind my own damn business, and even if the offer was valid they would never take it. I can understand his frustration. The entire family has shat on their relationship and even though they appear to be supportive everyone is saying horrible things behind their back, but its not a valid excuse for the way he behaved towards me.
So here is where it gets sticky. Thanksgiving is coming up, this year my FI is spending the holidays with my family. The Saturday after Thanksgiving, his side of the family (specifically the parents of the crazy cousin), are hosting an impromptu Thanksgiving at their house. Everyone is invited. I am extremely reluctant to attend because I am hormonal, and I am unsure if I will be able to hold my tongue if the cousin says something nasty. While I love my FI and the rest of his family, I don't want to say something I will regret or do something stupid. Should I just put my pride aside and go? Or should I stay home? What would you do in this situation?
