I want to move out of my boyfriends parents house.

I’ve been living with my boyfriend and his parents for two years now, and I’ve been wanting to move out for a year. Partly because his dad and I clash heads a lot and also partly because I feel like I need space from my boyfriend. I’m almost 20 and he’s 21 and I moved in pretty soon into the relationship. I love living with my boyfriend, but I feel like I need my space and I need time to miss him. It’s also just really hard living with someone else’s parents after just moving away from your own. We have two cats together and I don’t want to just leave them here either. I feel almost trapped here and I know it’s not necessarily healthy to feel that way. We’ve discussed getting our own place but it would be really hard to make it workfinancially, so my only option would be to move back home, which I wouldn’t mind too much. It’s just a stressful situation and I don’t know what I want to do yet. any advice is welcome.
