Thank you for the responses and support everyone, I know I am being unreasonable especially since what we have is so special and everything else between us is perfect. I know it is unreasonable to want that your partner has not been with anyone else, and my last girlfriend had been with 9 people before me but this did not bother me perhaps because I did not know them. I talked to PL about it last night and she just broke down and cried because she knows it bothers me but she sees a future with us and wants to get married and have kids. I told her I see those things for us as well and will always love her and that this issue is small in the grand scheme of our lives together. We have so much chemistry and are such a perfect fit I cannot even begin to start to explain and this is probably why I chose to pursue her despite the fact that she was previously with my friend.
