HELP!!!! BM has turned SIL against me!
Setting the stage: she's not really my Sister in law, she's my boyfriends sister. She was really close to BM while she and my BF were married because SIL doesn't have any sisters and the two of them were very similar. But constantly in competition. BM couldn't get pregnant because of fertility issues but SIL could and did; BM would get pissy when SIL talked about her pregnancy at ALL. After divorce, I heard all sorts of stuff about BM from SIL. mostly negative.
BM yelled at me a couple of weeks back claiming I was trying to become SD2's mother and push BM out of her life (I wish I had that kind of power!). Earlier that week, SIL had asked me if I wanted to go to a class at the gym with her, we were friendly etc. things were good.
BM and SIL have been spending a lot of time together (compared to before) recently taking thier kids on outings and such. Now SIL won't even say goodbye to me when she leaves anywhere we are together. At a family bday party she hugged everyone but BF and I. on Tuesday at MIL's she hugged everyone but BF and I, yelled good bye to him and nothing to me. She is cold to me. Makes negative comments about ANYTHING BF and I buy saying that we are wasting money (don't get me started on the $4 juice bottles she bought her kids (2 for $4!!))
Its not like her behavior won't come back to bite her in the butt later on, it will and I'll make sure of it. But what do I do about it now? BF said that he is going to say something to his mother about her behavior, esecially since he was told to act respectfuly towards her idiot of a husband. But I told him not to because SIL is perfect in the eyes of MIL. She usually makes excuses for the actions.
I've just been ignoring SIL, do I continue? Or what? Does anyone have experience with somethng like this? (I really hope not because its just crappy)
