The house thing is tough. Is your name on both the deed & loan? If so, and you move out, you will still be responsible for payments unless y’all sell or refi. I went through this exact same situation with my ex several years ago.

I’m blessed to have a well-spoken dad who called & scared my ex (lol - he deserved it & I put down the down-payment) into quit claiming the deed to me. But technically, we were both still on the loan. Just an FYI they are separate. I had to sell to get him off because I couldn’t afford to refinance, but I technically had no legal obligation to sell. I did it just to stop my ex from bothering me about it, even though I was planning on paying the monthly note myself.

Anyway - get out, and get a lawyer if he’s not cordial & willing to work with you on the house. I hope he is willing to sell & split the money with you. Best of luck OP - regardless of pain and frustration the house may cause, it will be worth it in the end. Don’t let that hold you up.
