There's no way I can compare to his girlfriend, I don't know what to do,help?

Lets call him Tim, friends for 2 years. Never openly flirted, never talked about liking eachother or anything when I was taken and he was single at the time when we met. I'm 90% sure he was interested in me or atleast admired me in some way, which I'm not afraid admit to admit anymore, i did too(I'm now single) 10 months later. The feeling never went away for me, he's now been with his girlfriend for about a year(they got together when me and my boyfriend were still together and we broke up shortly after). Me and Tim talk all the time, just about everyday, we share a lot in common and our convos just flow for hours. He's all i think about, I'm not interested in any other guys,(we're both students and 19) i just cant get him out of my head. And I get really doubtful about the possibility of ever even being with him, his girlfriend cooks amazingly,(i know it sounds silly), she draws beautifully, has an art scholarship and everything, and he keeps talking about her less and less (rarely ever did). I feel foolish when I think about it for too long and I just get really doubtful and criticize myself for thinking about something that may not even "be there" and feeling uncomparable because I have no profound talents like that(really not trying to sound self pitiful, I believe I'm an overall confident person) Any input or experiences with this? what do you recommend I do about it all?
