Me and my girlfriend took a break, she slept with someone, now I can't seem to love her.

Title is basically it. She was taking me for granted for a while, really treating me like crap. we broke up, came back to me asking to get back together, said she'd change, etc, I was overjoyed. I later found out she slept with someone in my absence of about 2 weeks (She was very, VERY intoxicated, not just alcohol either), and ever since I found that out I'm completely unattracted to her sexually and emotionally. I feel bad because I know she's trying, she will literally do whatever I say (I told her she's not allowed to do drugs or hang out with guys anymore) and she's really been taking the initiative to get us back as a functional couple. I just feel a mix of jealousy and anger and depression and insecurity, just weird unpleasant emotions when I think about her or talk to her, and she knows it.

Advice would be greatly aprecciated.
