Really confused

Hey, sorry for the long message, but this has been driving me crazy and would just really like some different opinions on what might have happened with this guy because I really liked him.

We had a really great date around mid/end July and we both seemed really into each other. His apartment lease had just ended, so he was planning to visit his family out of state after the weekend. He told me we should go out next weekend if he was back. Next weekend he let me know he was having to stay longer, but asked what I was doing the xx of August. I said that was the day I was leaving for a vacation, but named the date I got back and said we should do something then and he said absolutely.

I text him a couple days before xx August and he said he was having to help his friend move out, but he’d let me know if he made it back in time. I was kinda annoyed and let him know that we had planned that day 3 weeks ago, but we agreed on the next Saturday. He ended up texting me late that night to let me know he got back, but I didn’t answer till morning. We text for a bit that weekend and he asked what my week looked like. I asked if Saturday wasn’t good for him anymore and he said it was, he just wondered if I also wanted to do something during the week.

So he came over to my place Thursday and we hung out- same as before, we had a great time and I thought a great connection. Of course he said the next week he was leaving for his vacation (he did mention this the first time we hung out) but even had his calendar up asking what I was doing mid September. I just laughed. Also, that Saturday we were planning- he made plans with his friends instead. Where I’d normally have written him off as he just isn’t interested by now, I’ve been giving him a bit of a break since he doesn’t have an apartment at the moment and his stuff was hours away with the friend who was moving out.

Anyway, he told me when he was getting back from his trip, but he never text me. I waited the rest of that week and sent a text that weekend and made a joke. He told me he ended up going somewhere else out of town doing a favor for someone. He told me the exact day when he’d be back and said absolutely to doing something when he’s back and that he’d text me. It’s been like 4 days now since he said he’d be back in town and I still haven’t heard from him.

I guess I’m just wondering if he really is just that busy, but is still interested, or if he never really was and has just been saying these things.

A couple things to note are that his texting habits haven’t changed at all- he has only ever text just to make plans and that’s it which is totally fine with me.

We did have sex, but we did the first time and he still wanted to see me almost a month after that. So I’m not sure why he wouldn’t now.

I really don’t think it’s other girls because I don’t see how he could have the time for it. He really is in all these different places and is in online school. Plus the way he was with me the first time was a few messages, then suggest a date a while later and actually took me out. I just don’t see him having the time for that. I also noticed that when I “liked” him on this app was 3 months before he matched with me which tells me he must not be on it that often. I know I sound crazy lol.

Anyway, any thoughts would be really appreciated and happy to answer any other details! Thank you
