Feeling lost

I (22) have Been with my other half (24) on and off for 2 years - we split when I was pregnant but I lost the baby and we got back together - I don’t want to go into too much detail on that just know lots of tears lots of talking and him begging for a second chance - 7 months on we have been having a difficult couple months - I feel like we are at very different stages in our lives and there’s a few things that have happened that has shown me that things haven’t changed and he’s still very immature and not willing to take any steps to progress the relationship- he’s very angry and just doesn’t speak to me at all and our communication is very limited - we live in his parents house however when I’ve discussed renting elsewhere he has simply refused - I’ll missing my own independence as I moved out at 16 and I feel like im taking steps backwards - im thinking it’s time to call it a day as I would like to move out and he has literally told me im not allowed and makes me feel really guilty about a lot of things and I feel very secluded from friends and family due to this - I could do with some advice and also some reassurances that I’m doing the right thing, as I currently feel very guilty and selfish and I feel frightened to be alone but I think it really is what’s best for me 😫 I’m feeling lost 😫🫶
