About her: For pretty much anything, the best way to learn is through personal experience. Partying and relationships are no different, she went through the party girl shit and dated some assholes, and IMO that's the best way to truly appreciate someone that's good for you when you meet them. I would wager big money that she cares for you more knowing how much better you are for her than the guys that treated her horribly, than if she had never dated any of them and just met you. I know that's how I feel about my girlfriend and how she feels about me, we've both dated some really shitty people and it definitely makes us appreciate each other a lot more.

If that doesn't make sense, here's something pretty much anyone could relate to: think of it like taking a piss. If you just go when you need to, you don't think much about it (ie not having had shit relationships). But if you have to hold it until you feel like you're gonna explode, when you finally get to take a leak, you appreciate the hell out of it. You love the fact that you're able to take a leak because of how shitty things were when you had to hold it (holding it = dating assholes).

About you: I can relate to the feeling you've got, I'm guessing your sexual history isn't as lengthy as hers and you might feel like maybe she's a bit more attractive than you or something because she had an easier time meeting guys than you had meeting girls. The longer you're together, the more comfortable you should become with each other and the less you should care about her past. You also have to realize how insignificant her past really is, aside from making her appreciate you more like I said above, it really isn't likely to affect anything.

If you don't notice yourself being less and less concerned with this as time goes on then you need to seriously re-evaluate things. If you don't, you run the risk of losing someone who was great for you, and you may not fully realize it until you're with someone who is terrible for you. Have you been in a shitty relationship before? If you haven't, it might be harder for you to work past her past because you may not fully realize how irrelevant it is.

It's unfortunate for her that she was raped after she got overly drunk (yes she was raped, not "letting herself be taken advantage of", unless he was as drunk as her then it was a rape) but you shouldn't be directing any of the blame for that to her. Realize that it is was 100% the fault of the shithead who raped her and focus instead on how you'd like to pummel the guy for doing that to her.
