<human>: Give me the gist of the text in a nutshell

So, as you can probably guess from the title, I'm Bi and I've only recently come to terms with it.I have told my parents, and they were somewhat supportive. But there is this guy I really like, let's call him A. A and I are both on our towns Track/XC team and we're both Varsity so we see each other everyday. I would consider us to be good friends. I have already come out to him, and he dealt with it rather well. The thing is, he's the guy I have a crush on. However, I've never been in a relationship before and can't tell if this is just loneliness or something more. 

The thing is, I don't know if A is bi or not. He could easily get any girl in the school if he wanted to, but he remains single. He also seems like he is bi but can't comes to terms with it as when we were talking after I came out to him, he seemed to know about it better than my straight friends. So should I tell him that I have a crush on him, or should I just hold it in?
<bot>: I'm bi and can't tell whether to come out and say I'm crushing on my possibly bi friend and also cant tell if I'm just lonely or have actual feelings for the kid.
