<human>: I don't want to be too long on here. I'm dating a wonderful woman who I am in love with and intend to marry. She is a single mom without custody and we live together. In a lot of ways, our relationship is perfect. However, there are some things that haunt me. She has been in a lot of abusive relationships in the past. She has had kids (obviously) with an ex who was cold and distant. She has been raped several times. She used to work as a stripper. She was in a horrible abusive relationship with a guy who cheated on her constantly and would have her perform in group sex acts. 

Anyway, the part that bothers me is that I know she has been with and had sex with all of these people. I wouldn't mind so much if they were nice, normal people, but they were horrible assholes and she still was with them and slept with them. Like she would get into physical fights with guys, they would lock her in rooms, and then the next day they would be having sex. She even had sex with them after breaking up so that they would leave her alone, even though she didn't want to. I just don't understand how someone can do that.

Anyway, I feel really shallow about this I want to get over it. But it haunts the back of my mind and makes me feel sick to my stomach whenever I recall some of the things she has done. How can I work through this? I have tried talking to her about it but I just come off as insensitive. I want to understand but I've never been in a situation before in which I was so degraded so I don't understand the mindset.

Give me the gist of the text in a nutshell
<bot>: My girlfriend has had a lot of terrible abusive sexual relationships in the past and it bothers me. How do I get over it?
