Some Advice?, for a noob... Options

[Weary Traveler]

Right, first I've got to explain something because its semi important: what I've got to ask about has to do with relationships and if you give me some advise that would be awsome but please put it in semi simple terms considering when having to do with relationships I am a noob in the worse for of the word. I mean uber noob elite. 16 and I have never had a girlfriend, or boyfriend for that matter, I've never been on a date and until last sunday had never kissed. so you can see that as I said, I am the uber noob. the only people worse off then me are prudes and morons. anyway back to my problem...

There is this very nice girl named Jenni that I know. A wonderful person and we had been getting along very well, as in my first kiss last sunday very well. So I decided that I would ask her out firday, which I still might. the problem is that she had been dating this guy named Dan, he's a complete ass and she had broken up with him for cheating on her with anouther girl. but it seems that I think yesterday they had gotten back together because she "loves him and has come to expect guys cheating in a relationship" that sickens me. it seem that any other relationship she has been in ended in the same way, the guy cheating on her and she's come to expect it as normal. If there is anyone here who doesn't find just that sick and twisted then they need some readjustment. My problem comes that I still really like this girl and I don't want to see her with this ass but I don't know if there is anything I can do. I would still go ahead and ask her tomorrow but I'm pretty sure the anwser would be no. I could wait for the ass to mess up again but she might just accept that as normal and let it go. I don't know what to do. Its a tough sitution because I want to help a friend and get a girlfriend at the same time. for some reason I doubt its going to happen.

Any advise would be greatly appreciated. thanks.
