How do I get over my girlfriend's past?
I'm 21 years old, and my girlfriend is 20 and this is our tenth time dating, every time I broke up with her. I was her first, when she was 16 and I broke up with her eight months after it happened, and between us dating she dated two other people, and slept with them both. I have slept with about 20 people, so I shouldn't get upset with her measly 2 other people, but I get really bothered. She's asked me numerous questions about my ex's and my past and she says it doesn't bother her because it's my past. I don't ask about her past because I don't want to know. But somehow it keeps popping up. I am in love with this girl, but I feel like this is driving a wedge between up. I can feel it eating away at me, and I want it to stop. How can I get over this, so we can focus on us?
