Search Results: why do guys move on so fast

Few months ago I met this one guy. He asked me out, we instantly liked each other, met up few more times. Last few times we acted like a couple and everything seemed great. The problem is, during this summer, we can't really see each other, because right now I'm in my hometown, and he's living in other town, that I study in, which is quite far away. The thing is, last time we met up almost a month ago, and after that I texted him first few times (and I usually don't really text first), but after that I never heard from him. It made me feel like he had no interest in me, even though during our meetings he was the one who showed more interest. So I thought fine, I will move on. For over a month now, I worked on loving myself, doing things I never done before and etc, because at some point this almost-relationship hurt me, because, I never had a boyfriend before and it made me feel insecure, that suddenly he seemed to lose his interest.
So this guy likes to travel a lot and has a lot of activities (that's why partly I justified him for not contacting me). This September he's planing a few week trip in Spain, and he's asking people to join him. If this would be happening a month ago I wouldn't even hesitate and refuse the idea of going there. But now, as I started challenging myself more, I thought to myself, why the hell not? I always wanted to travel to Spain.
Would't I come off as a little clingy or desperate if I would tell him, that I wanna go? Now, just to be clear, I would travel there not because of him, but for myself, because I think, that this trip would be great challenge for me. I don't even know if I like this guy in the same way anymore, and I have no idea, what he thinks he and I have (or don't have). He's interesting person to talk to, so I know that communicating with him won't be a problem, but it's just the fact that I don't know how to feel towards him.
I need to decide very soon, because if I wanna go, I need to book airplane ticket really fast.

In a nutshell, my ex boyfriend and I started things pretty fast. We've been together 3 months. He's got some personal issues going on his life, but other than that, he's a really great guy. Fun, caring, smart. I was the one who was continuing to move a bit fast for him. He was used to going at his own pace. Just last week, he told me he didn't want to deal with it anymore, that he just didn't share the same feelings for me as I did for him. I think it's possible he was just overwhelmed with everything going on, and I wasn't making things any easier. I didn't realize that what I was doing was pushing him further and further away
The brief break allowed us both some space, and just recently we agreed to meet up and talk. It was a nice few hours together. I decided to invite him over yesterday, and we actually had a really good night, no tension, we were able to talk for hours and laugh. I felt we were actually, for the first time, getting to the core of each others personality. He thanked me for letting him stay and he agreed that it was easier to just let things flow and it was all cool.
Does this mean he's possibly reconsidering his decision to break it off? It's only been a week so that's why I'm curious to know if this new approach can actually turn things around? And the vibe I felt was a positive one.
