Looking For Advice On A Sort Of Relationship

I'm just looking for some advice in a situation I'm currently in.

Its like this, I'm never the guy who does anything wrong, I'm friendly, helpful, I'd give the shirt off my back to anyone in need, but I do second guess myself a lot, especially when it comes to relationships, Gods only knows how many I've been in, and 95% of the time it's her/she who cheats on me, and I really don't get it. I know being the good guy, all the time sucks, but I really can't stand when there are guys who have someone so meaningful, something so good then they go and mess it up. I don't get why they do it, people like me who would do almost anything to be...well lets say "happy" don't get the opportunity and it really sucks. Anyways, recently I had given up on even trying to find happiness, deleted POF, match.com, things in the real world seem so much harder then the online world after countless attempts at keeping an honest relationship. Now here's the situation, a friend did some cheating on his girlfriend and she found out, she then made a pass at me, and needless to say I didn't stop her, I more so gave in and played all the right cards, but the problem is...she's willing to forgive him and work things out...which leaves me once again confused, lost, dazed, things like this don't happen to me, at all. Now that it has, I don't know what to do...I obviously have strong feelings for her, but I don't want to hurt her, or give up on her, and I know doing the right thing, is the best option at this point, but is it really worth this much sadness, depression and loneliness? Any ideas or helpful advice would be greatly appreciative, thanks.
