My sister in law (32f) is the one who introduced me to her brother, we were friends for a little while and I was going through a hard time so I stayed with their family. I paid rent every month to their mother for a room (before we got together). She would pay for whatever they decided they needed which was fine. But SIL decided to put the electricity in her name and she expected me to pay it. It went fine at first because the amount I paid in rent covered that and more, but it got to the point in dead winter that it became almost $900 and I only paid my regular amount. ($250). She threw a fit and said it was my responsibility. All the while everyone in the house paid rent but her. After that went down she started calling me names like fat c*** and other disrespectful things. (She’s by no means small). She moved out. (Everyone was ecstatic). I would see her driving by screaming profanities at me every single time she saw me. She would also threaten me. Whatever I’m not in the least bit afraid of her, but this has continued for years. Most recently she called my job and told them that I assaulted her on the property of my job, I don’t think she even came to my job. She’s been caught sitting outside of my home for hours watching me. It’s gotten so crazy that I’ve had to put paperwork on her for stalking and harassment and online abuse. I found out I was pregnant 3 months ago. She had the audacity to tell my husband (34m) she wants to babysit and throw the baby shower. My sister is already doing it. My husband has a hard time so he told her we weren’t having one because he also doesn’t want her there. She keeps bringing up things to my MIL about getting a crib to babysit and a stroller. AITAH to say that she will absolutely never ever be near my baby and she has to be absolutely delusional to believe that I would allow that? It kind of feels like she thinks my husband will let it happen but he won’t. I don’t trust her anywhere near my child. I would also like to throw in that she has a kid (9f) who when she was a baby used to drive around drinking with her in the backseat. She does struggle with alcoholism. I just am wondering what other people think. The most recent incident happened is December, so it’s not like she’s grown or tried to apologize. AITAH
