Is this just me or am I plain Stupid?

Thing is I keep kissing this same girl when I go out of a weekend because she is in my cl, when we do its really pionate and great, so I began to text her and stuff and started to get to know her, however I just cant move it to the next level, I don't know if its subconscious or not because in reality, I hate to say it, I cant really be with a girl properly unless she is exactly what I have been looking for ( and I know, highly unlikely ), I want to get with this girl but I cant bring myself to commit or back off as I know either way I will probably regret it. PS My friend made this quote regarding the issue "grow some , she's the fittest girl in collage, your a handsome ungrateful who doesn't appreciate how hard it is for someone like me!" so yes I will understand any abuse that is likely to come my way. Any tips guys?
