I really need help... I was engaged to be married in 2006. I had everything ready.. my dress, my girls had their dresses, and 3 months prior to the wedding, my finace told me he was cheating so everything was called off. Some of my bridesmaids then, including my sister & I are not close at all. Another one of my bridesmaids (my cousin) sold her dress because back then, she was pregnant. Well I have moved on and am engaged to be married this June and rather than planning another big wedding, we're having a destination wedding in Florida. My sister and I had a huge falling out over the presidential election... where I was voting Republican and she got very angry with me and wrote me a nasty email, basically telling me that she wrote me off as her sister and deleted me off of all of her online accounts (facebook & myspace) she's very childish like that. Well we have reconciled to some extent... however, I think I have spoken to her twice on the phone since then and she may leave comments here and there on my facebook page but we really do not talk. Well recently, she found out I was having my cousin, and 2 of my best friends in the wedding and she called my cousin very upset that she's not in the wedding. I feel bad, and my mom told me I needed to have her in the wedding, especially since she bought her dress (3 years ago). I do not feel that just because she's my sister and has a dress from my previous wedding means I need to have her in my wedding.. especially given the fact that since then, we had a major falling out and never talk. I already asked her if she would be willing to read from Corinthians at the wedding and she said she didn't want to read, she doesn't like to read in front of people. I have tried to still include her to make her feel not completely left out but I don't feel close enough to her anymore to have her as my bridesmaid.
Should I suck it up and put her in the wedding to avoid conflict or should I stick to my guns?
