I know I can't change what she believes, but I just think, in my opinion, its kind of ridiculous for that to be a dealbreaker if you really love someone and want to spend your life with them. Cheating, without question, that's a deal breaker. If she had slept with guys while we were broken up, would I be hurt? Yes, at first. But I would be able to get over it if I knew she wanted to make it work and wanted to spend her life with me. My love for her would overshadow the temporary hurt of her sleeping with someone else. She told me she had made out with some guys during our breakup, and I told her I had made out with some girls. She didn't care about that. But it was me having sex with one person that made her so upset.
I'm just saying if you really really love someone and want to be with them forever... sleeping with one person during a BREAKUP shouldn't be a dealbreaker. But that is just my opinion and I can't change how she feels. Who knows though, she is upset about me sleeping with someone, but I'll never truly know if she would have been able to get over that and stay with me because I didn't tell the truth when she asked. Man, that what if scenario just keeps haunting me. What if I had told the from the beginning? I'll never know.
