<human>: About a month and a half ago I met a guy and we dated for a few weeks before school ended and we got really busy. Things were going really well. We were hanging out a lot and we both expressed that we really liked each other. I haven't been able to see him for a couple weeks because we were both traveling, but the whole time we kept in touch and we agreed that we'd hang out once we were back in the same city. I came home yesterday and I suggested hanging out last night, but he said he was too tired and didn't seem all that excited. He has a huge project he's been working on, so I understand if he's been really stressed, but I'm hurt that he didn't want to hang out with me. I'll admit though that I was being pushy because I really wanted to hang out with him. This is so different from before where he would practically beg me to hang out with him, even on nights where we both had work to do, and during finals when we were both really stressed out, we made time for each other. He's leaving tomorrow for a couple weeks so yesterday and today were our only chances to hang out for a really long time. I don't want to let this time pass without seeing him because we didn't date in person for very long in the first place, and this will be forced to either be a long distance relationship (which sucks) or we'll lose touch (more likely), which I don't want either. Mostly I'm just disappointed because this is our last chance to hang out for a long time, and we haven't seen each other for two weeks, I thought he'd be more excited to see me. Is this something I should bring up with him? I don't know if I should be pushy to hang out today or just let it go, because it kind of seems like he lost interest. But it doesn't make sense if he lost interest. Just a few days ago he was texting me telling me he missed me. The last time I saw him he said he really liked me, I don't understand how things could've changed.

Can you summarize the given text in a few sentences?
<bot>: Guy I really like doesn't seem to want to hang out with me, despite things going really well between us a couple weeks ago.
