Okay my MIL and SIL moved in with my husband,child,and I in our 3 bedroom home to get away from her abusive husband. Had no issues we enjoyed her living with us. She didnt like that she had to share a room with her daughter (we had an almost 1 year old so she kept the baby's room). After a month with being with us for free, she packed all of her stuff while we (husband, child, and i) were out at dinner and moved back in with her abuser. Yes I was upset but I didnt take it out on her.

A year later she moved to a different town, and she begged us to move too. So we rented a home for a year in the same town as her. Before we moved back she begged us to let her and her kid (who's an adult) move with us back into our home our 3 bedroom home. I said yes under one condition that her kids cat cannot come with, because I'm crazy allergic to cats. She throws a huge petty fit. and tells our child that she will probably wont get to see her again bc of mommy. SO she talks me into the cat coming too. I then pay for the largest uhaul and loading day comes while loading she complains about how she wont have enough from for her stuff, so alot of my things were left behind. Now shes in my home with her adult kid. This time lasted for much much longer because out child didnt have a room. Then the petty comes back because everything bad in her life is my fault. like her cheating on her friend with benefits was my fault. So she begins to talk major crap about me behind my back to my sister who she thought wouldn't tell me the horrible things she said about me.WRONG.I became pregnant with twins and my serverly neglected step son comes and lives with us. MIL&SIL has to move out. MIL - "if you ever need ANYTHING just call me." I loose one of my twins. Now trying to help parent a child that I'm having the hardest time bonding with. on top of my high risk pregnancy, type 1 diabetes and a toddler. When I call MIL she is too busy!? (I know alot of this is my fault. I know the magic word that would help me with my MIL problems and that's its NO) before the pettiness we were really good friends.
