<human>: Okay, here's the story. I have had three relationships across my life so far. I am in my senior year of high school. Almost two years back, I met my current girlfriend. About two weeks previous to me asking her out, I was about to start a relationship with a girl who had made it obvious that she really wanted to be with me, but neither of us had said it out loud. Enter my (not yet) girlfriend.  
  
She is everything I want and more. She has a great personality. She's very considerate. She's really funny. She's a gamer and a geek. She's extremely intelligent. She's kinky in the same way I am. She's everything I want... but too soon.  
  
Throughout our (almost two years now) relationship, she had brought up her (many) past relationships. She brought up her sex life. She brought everything up that could have made me curious of what I never had.  
She is head-over-heels for me. She recently began discussing that she wants our relationship to continue long-distance if we both go off to college, hoping to settle down eventually. But I am still too curious about the relationships I could have had. I'm curious about the relationship that could have been with the other girl that I have known nearly my entire life.  
  
I know that if I do end up breaking up with her, I will most likely never find a girl like her again. If I don't end up breaking up with her, and we end up going long term, I will always be kicking myself because of my curiosity about relationships I may have had. I have never had sex with anybody but her, even.  
I have touched upon this subject lightly with her before, and have found out that she isn't okay with an open relationship and she also would never want to take a break in the relationship.  
Based on how well our relationship is going right now, it is unlikely that we will break up any time until we go to college, and based on what she has said about wanting to continue long-distance during college, it is unlikely to break up even then.

Can you condense the text into three sentences or less?
<bot>: I know that if I break up with her, it will kill her inside, and if I don't it will leave me with too much curiosity for what I could have had with other women.
