Input: I'm in love with my best friend, but she doesn't feel the same. How do I live through this? -Details in comment.

I'm 17 and I have my first girlfriend; she has had several boyfriends before me, and she's not a virgin. That doesn't bother me, but when I think about her having sex with the last guy, who she was really in love with, I feel really insecure. How can I overcome this feeling?
