I HATE my SIL (brother's wife). Now I know that's a VERY strong statement and it's just how I feel. She's not a good person AT ALL! Background on the situation: She has a bad habit of running away. I mean literally. And it's a frequent occurrence: she'll stay home for 2 weeks or a month; my brother never knows how long she'll be home. And to make matters worse they have 3 small (under 5!) children. She'll say she's going outside to make a phone call or running to the store and disappears for days or weeks. Now none of this directly involved me, so I stayed out of it, until my brother's car broke and he asked me to pick her up one time. Being that I adore my baby brother very much and I live closer to where she was, I agreed. On the trip to bring her back home, she giggled and asked why I even waisted my gas to come get her and talked trash about my brother the whole way. Not only that but she's tried to get FI's "attention". On more then one occasion he's come home and handed me his phone and asked me to take care of the situation. Apparently, when he didn't txt or call back, she didn't get the clue. She's stolen money and things from my home; talked bad about me to MY children and friends. She even LIED to FI to try to get him to break up with me!
Well, my main problem is that-although it's killing me; I'm not inviting my brother and his wife to our wedding. I can't *just* invite him, and I REFUSE to invite her. And my parents are trying to push me into "fixing my issues" with her so that my brother can come to the wedding. I cannot even stomach the idea of having a friendship with her. I am polite when we are at family functions, although I don't engage her in convo, I answer politely when she speaks to me then walk away. But that's as far as I am willing to go.
Should I just suck it up and invite them? I do NOT want her to be there, but like I said: I adore my baby brother and all my little nieces. I just don't need drama on our wedding day.
