My SIL is a pain in the ***. We've know each other since kids. We've had years of friendship and now years of conflicts and drama. The only way our relationship is tolerable is because we (I) keep it on a strictly family level. We don't mingle friends.
Because of the power of facebook we are both finding people we both went to school with. I found most of these people about 2 years before SIL did because I was on FB first. Therefor I've now developed new friendships with them.
One mutual friend in particular, I'll call her Dee.... because of Dee I've made a lot of new friends with a group of girls Dee is close to. Dee also knows my SIL and now my SIL is using Dee to get in with the group.
Do I have the right to flip out? Meaning: SIL throws herself a b-day party last night, I was invited but declined (because I don't want to mingle friends) BUT SIL invited Dee too. Dee told me she was going but didn't want to stay long but she was also bringing a group of our friends with her to the party. I got really upset. SIL is the type of person who uses any opportunity to think everyone is her new BFF's. I told Dee everythinhg I told you guys, how much conflict ive had with SIL and how I can't mingle friends with her but Dee didn't change her mind and took the friends there last night with her.
I can't stop thinking about it. What if my worst nightmares come true and SIL becomes part of that circle? What would you do? Do I have the right to be upset this is happening?
