Feeling deflated from lack of love

So I (M) don't know what I'm expecting. I just want to say what's on my mind because no one ever understands me and I'm kinda in the closet bisexual so I don't really have anyone to talk to. I haven't been very social for a while but just recently started university and have been meeting heaps of new people. The problem is that I don't feel like I am connecting with any of them and I haven't been in a relationship for a long time. Mainly because I'm afraid of exposing my sexuality to people and also because I feel like I'm not connecting with people very well. Most people want to go to clubs and all that, stuff I'm not into. Well recently I met a really nice guy who I began to talk to and he seemed to have given me a lot of his time in person when I see him. Yesterday I added him on fb and messaged him. He replied like hours later and didn't really carry the convo. Makes me feel so deflated because he isn't into clubbing and all that and I'm attracted to him so I was hopeful. Ugh. I feel frustrated.Sorry it isn't all structured that well, I just wanted to get the thoughts out of my head.
