My sister (33) and I (36) got into a disagreement that turned into a huge conflict a few months ago. At the time she had been living with my family (husband, 3 kids) for about 6 months and planned to stay indefinitely but when we got into this fight we asked her to move out. She put up a fight and essentially we had to tell her we would proceed with eviction if she didn’t leave on her own within 30 days. (There were a lot of conflicts within the conflict, boundary pushing etc during this time but I’ll spare the details here.)
Since she’s moved out she’s tried to maintain contact with my oldest child (14) with whom she was closest. My husband and I asked her multiple times to stop contacting him. We just needed a break from her and my son was put in the middle of the initial conflict when she attacked my parenting of him (he overheard her attack) so he was feeling “off” with her too.
My sister has continued to make contact with him despite us asking her not to. I blocked various channels but she kept finding ways. For example, she used her substitute teacher position to work at his school and brought him a birthday gift there. She’s also shown up at my house when my dad was babysitting to see my younger kids. The last time she tried talking to him was on her boyfriend’s PS5 account.
I finally told her that if she kept contacting him I would make a police report and possibly get a restraining order. She’s accused me of being controlling and threatening/harassing her despite the fact that the only time I’ve reached out to her in 4 months has been to ask her not to talk to my child. Am I overreacting to consider going to the police?
EDIT TO ADD: This is the context of the fight-
My sister lived with us for free including all meals and utilities, family gym membership, vacations, etc in exchange for 10-15 hours of childcare per week. her and i got in a fight over something stupid (I asked her to help with the basement reno I was doing for HER to have her own space and she used the wrong paint and got mad because I called her on it and used a tone of annoyance with her and she didn't like that. I apologized afterward but she was still hurt) Two days later she asked me to start paying her for childcare on top of the free room/board/meals etc. I got pissed because I felt taken advantage of. She also saw a rant I was texting to my husband (she read my texts) and told me that I have work to do on my "resentments"
...and from there we got into a yelling match during which she said "there's a million things i could say about your kid upstairs but I won't" (this is the 14 year old i'm talking about. and he heard her say this. and was hurt by it).
We tried negotiating with her to continue living with us for example, she pays rent and we pay her per hour for babysitting. But the trust was broken because i felt she used my parenting against me and I felt judged and watched every time she was around me and my kids. So i decided it wasn't healthy for me and that living together was only going to hurt our relationship more. I gave her 30-60 days to find a new place. She was cruel and disrespectful of my space the entire time she stayed. I wanted to work on our relationship without the complexity of living together but she was pretty shitty in the end that it didn't work out that way.
