My mom has two sisters, one is fine, the other one is seriously crazy and needs therapy! I don't want to invite the crazy one and her two daughters to my wedding. My mom's sister is 10 years older than my mom and very jealous that my mom has grandchildren (from my older siblings) and now I'm getting married too. Her two daughters are 31 and 33, single, never married, and no kids. They are mad that their youngest cousin (me) is getting married before them at the age of 26. They have nothing nice to say about my mom and I and have not been supportive during my engagement and wedding planning. When I first saw my two cousins after getting engaged at a family dinner they never once acknowledged that I was engaged. And I sat with them and talked for two hours! My aunt has made the situation much worse in the past month by sending rude and dramatic emails to my mom and I. In April, a week before my b-day she emailed my mom and cc it to me, saying I am destroying the family by not including my cousins in my bridal party and that nobody talks about the wedding to us because they aren't a part of it. I NEVER planned on having my cousins in my wedding...we aren't that close. I would never expect to be in their weddings either. My mom and I choose not to respond to her email. Then, last Saturday my mom's other sister had a mini family reunion at her house with some out of town relatives. This was the first time we had all been at the same place since the crazy email. My mom said hi to my crazy aunt and gave her a hug, trying to keep peace. I didn't go near my aunt because I have nothing to say to her and she stayed away from me. When my two cousins got there they never came in the same room as my mom and I. Then on Tuesday (2 days ago) my aunt emails my mom again and cc's it to me. She says "Goodbye. You lost a sister on Saturday May 7, 2011." WTF?? She is so dramatic and just trying to cause problems. My mom is hurt, I'm pissed. I don't want to invite them but my mom says we should, that way the decision is on them and they can't say "oh, you didn't even invite us to your wedding." I say, I don't care...I don't want them there. My mom doesn't think they will come anyway, but what if they do? I don't want them around me. They are toxic and have been trying to ruin my happiness and my mom's during this time for us. What should I do? What would you do?
