I have a sticky situation which I could explain for hours but I won't, I'll try to keep this as short as possible!
I am 23 years old. I was best friends with a girl from the age of 14 to 21. We made the mistake of becoming roommates in college and lived together for three years. This helped me realize that she is a very selfish person and I started to hate her. She's been dating my brother the same amount of time that I have been dating my fiance (almost 6 years). So she's always around whether I like her or not. We grew apart and went our separate ways but I still see her ALL the time because of my brother. We are very civil with each other and actually have fun when we hang out. But in the back of my mind I know who she really is and how selfish she is and I don't like her character.
We don't talk about our "falling out". I think that some day in the future we may become close again because we will be family (my brother is proposing in a week), we will probably have kids close in age, and we have fun together. So I wonder if I should have her in my bridal party because we have a history together and will probably be close later on in life.
When I write this out it sounds stupid. I shouldn't have her in my bridal party because she has screwed me over so many times and has never been there for me or cared for me feelings. I have always been a people pleaser though and I would rather sacrifice some things to risk hurting someone else's feelings.
When my fiance and I got engaged she was hugging me and telling me how excited she was for us (which seemed fake). I feel like she is waiting for me to ask her to be a part of my wedding and then I'm like wtf, how can you even expect that with how you've treated me in the past?
My wedding is 9 months away. I have some time to think about it but I don't feel like my thoughts will become any clearer with time. Will I regret not asking her? I'm not the type of person to sit down and talk about my feelings with others so talking to her is not the answer for me. Has anyone ever been in a similar situation? If so, what did you do or what would your advice be for me?
