Why does my (F20) boyfriend (M22) not want to hangout?

My boyfriend and I have been having a lot of issues lately. Mostly revolving around the fact that he wants more alone time. We ended up breaking up because he felt that he wasn’t making me happy, because he knows i’m someone who really values quality time. Before this, in the past, he had previously been pretty flaky with plans and never really wanted to do much.

It confuses me because he always seems to be too tired to want to do anything with me, and will cancel things to make plans with his friends instead. And I mean, it’s really confusing because first of all, besides this, he’s pretty great at everything else. We never fight and he’s really kind. Second of all, it’s not like we were hanging out that much anyway. With our schedules between school and work, we would only really get to have sleepovers. In an adult relationship shouldn’t we be going on dates and doing things? Instead of me coming over at 11pm, going to sleep, and then leaving at 8am for class? It’s even on the days we have off. It seems like he doesn’t want me there unless it’s the middle of the night.

We ended up talking, and decided that we were going to try to work through things and get back together. But now i’m feeling hopeless because he wants to see me less than before, and I don’t really know if it’s worth trying anymore? Am I being unrealistic with my expectations, or is it because he doesn’t like me? I’m confused.
