In law living with us is hell...

Hello, hoping to get some advice from you ladies. ☺️

Here’s the story;

Myself and my fiancé have been going through a rough time since November, he got let go from his job and ended up in the hospital on and off and soon after that I left my job to take care of him. Late December we got approved for government help and we were fine (kinda). My fiancé’s dad was very “concerned” with him being in and out of the hospital so he wanted to move in to “help out” I was 100% against this because I know how his dad is and it just wouldn’t be a good decision...well fast forward to now and it’s hell 😔 He is constantly holding his help over our heads, telling us he didn’t do this for himself and that he has lots of places he can move in to (then move...lol) he doesn’t help with anything around the house and he treats us like children. Also, one thing that really pisses me off is we both quit drinking and smoking weed last year because it was interfering with our life and his dad offers him beer and weed all time and now my fiancé’s is going back to his old ways...i just really cant deal with this. I have issues with parents holding things against me, I don’t like feeling like I owe someone for something that wasn’t my choice nor asked for. Am I in the wrong here? Should I relax and ignore everything that is going on or take action? My fiancé is bothered by what his dad does but is a little more slack with it because well it’s his dad and he also doesn’t do any of the house work so he doesn’t know what it’s like picking up and cleaning for two grown capable men. I’m just so lost and alone on this, I feel like I can’t speak up about it to his dad, and my parents are pressuring me to move out and just leave it all. What do you think I should do? Any comments are appreciated 🙂
