17 year old looking for some help.?

How should I go about finding a good girl to date? In my short life I've had only three girlfriends. All of whitch have cheated on me within weeks of dating. I think that this was a combination of some crazy girls or maybe drinking because I'm always very kind and caring due to my upbringing. The major problem is that I can't seem to get nice girls to like me. I always attract very beautiful but very slutty girls. Which I've personally never even tried to have with(still a virgin) I struggle with the thought that it might be who I hang out with. Half of my friends are big on parties and drink a lot and have copious ammounts of . Personally I find this a corrupt lifstyle and permiscuous incites neasua. Do women really like the bad guy? Or do they not even know I'm nice cause the actions of my peers reflect upon me. I've always been told I look handsome by my friends moms and older women so I don't think that is an issue. I also have very large eyes but they are a very light shade of blue... is that unatractive? (Sorry for this rant-like article laced with grammer issues and the pretentious ending where I give myself a complement)
