Search Results: my nervousness is back

I'm a Belgian girl currently studying in the States. Before I left for my summer break, I met a guy and we kinda fell "in love." It was a short thing, only some nights, we had no sex, but there was a lot of kissing and talking.
We were clearly crazy about each other and there were feelings involved. Somehow we lost contact over summer, but I couldn't forget him. He's not a person who likes texting and he doesn't have any social media accounts. Everyone I know would describe him as a bit strange (but still "cool") and different. Anyways, when I came back to the US I sent him two messages that I'd like to meet up and recieved no answer ( I know from mutual friends that he may have problems cause he quit his studies.) Three days ago I bumped into him. I tried to hide my nervousness while we were with a few mutual friends. I also ignored him because there were so many people around us that know about us so it was a pretty awkward situation.
But when I wanted to leave he said he wanted to talk to me...
The first thing he said was that he received my messages. Then he said that he was really busy over the past few weeks but that he'd love to meet up with me again. I tried to show no emotions as I was simply shocked and tried to hide my feelings... He said again that he'd want to see me again but that he might be busy the next couple of weeks, but he said he would text me. It was maybe a 30-60sec talk and we were walking so he didn't really look me in the eyes or anything, but as I mentioned above, he's def not like most guys I know.

I don't think that he's an asshole but well, who knows. I think he's having a lot of difficulties with his life right now (don't think he's really busy.) I also really appreciate that he came to talk to me. I'm pretty sure something will happen sooner or later because what we experienced before I left was unique.
by the way, he's 22, I'm 25.

I just hope to hear from him soon as I'm getting crazy & need some support / want to hear your opinion!!

I've always been this way... But I never respond to messages right away UNleSS of course it's my best friend or parents and there's no nervousness involved. But if I'm talking to a man I'm interested in, i am quite nervous and like responding with good messages, so sometimes I wait half hour or hours to respond.. Like this guy on Facebook I've been messaging.. He messaged me last night and I was awake.. I was super excited to see a message from him, but I didn't want to respond right away because I loved the feeling of being messaged by him, thinking of what to say, and just taking my time with it all. I responded not til this morning. I hate messaging someone back to back within seconds because the conversations usually die faster and I am not as careful with what I choose to say. I also love the anticipation. Is anyone else like this or am I weird? Does it look bad?

and this is just normal conversation... Not like, if I'm meeting someone and I need to respond quickly.

This shy guy seems to be showing more and more nervousness everytime I see him. So, I don't know how exactly to take him.
I don't know if that's a good or bad sign.
