In need of advice

My kids dad & I have been split for a year, but we live together (separate rooms), all week he has been trying to sleep with me we haven’t been sexually active in a year around the same time as our breakup, i decided the split because their was abuse in our relationship I could no longer with stand. Every time I tell him no it feels like he becomes more aggressive, I don’t have any family as we moved states away too get away from his

But I feel like I loss my in the process also. I’m trying to save up enough to move out hopefully back closer to my family but when I talk about moving out he always says I’m trying to keep the kids from him when I offered for him to just take me to court for a court visitation order that way legally he knew his kids were the last people I wanted to keep from him. He refused! I took what little savings I had went to an extended stay my son took the split the hardest he cried 4 out of 7 of those days so I decided to go back home. But I hate it! I smoke 🍃

Due to my anxiety being at an all time high. Idk I am just so lost & tired
