Is it normal that nobody else measures up?

So there's this guy, I've known him since we were freshman in highschool. Were both freshman in college now. The first day I saw him I instantly fell in love. Were casual friends and run into each other at parties and stuff, and he always flirts with me and all. Well we got pretty messed up at this last party and he was telling me about all his problems and I felt an even stronger attraction to him. I've come to the realization that I like guys who are dark, have problems, and don't know what they want to do with their lives. I guess because I am the same way? And the fact that were not together really gets to me a lot. I think about it all the time. I really can't see myself with anyone else, and when I look at other guys I don't feel what I feel when I think about him. I feel this deep connection that almost transcends everything in the physical world. Like we were destined from the start. is it normal that I have liked the same guy for 5 years, felt instantly bonded to him, and am attracted to his dark personality and multitude of problems?
