Moving in together

So I moved in with my boyfriend of three heard about two months ago. We moved into a flat with a lot of problems so ended up moving into a lovely house. However, I think im starting to realise that the problems were deeper than just where we were living. I have this lovely house and still im not happy. I moved in with him so that I can see him more. We're only young so we have a lot going on and didn't always get the time. He works full time and I work part time as a supervisor and im also in university. Living with him is abit of a struggle financially, it meant me moving jobs to get more hours while continuing with uni, but like I said it was what I was willing to do to spend more time with him. But now I just feel lonely. He doesn't ever want to do anything, he never wants anyone to come round, he's usually being moody.. Im a happy person but now I dread every day.. Im scared of leaving Incase o regret it, but I don't feel happy.. I feel like he doesn't appreciate me or take my needs into consideration when im putting so much into this.
