My girlfriend and I are both bisexual girls and have been together for almost a year. We love each other in such a deep way we never knew was possible. She's my best friend and we both know we want to spend the rest of our lives together. Unfortunetly, I hurt her badly a few months before we started dating and she still isn't over it. We both knew and admitted that we had feelings for each other, but we both had boyfriends at the time. I would have broken up with my boyfriend in a heartbeat to be with her, but she didn't want to hurt her guy's feelings and she insisted she loved him, even though he ignored her most the time. I was really hurting, and I decided to get my mind off it in the worst way possible. I had sex with my boyfriend even though we had been dating for only a few weeks. It's my biggest regret in my life and I'm ashamed of it. My now-girlfriend (my best friend at the time) found out and got insanely upset. She later told me she almost killed herself that day. She feels like I betrayed her trust and cheated on her. There was something special between us. She's still hurting, and it pushes her farther into her depression. She brings it up a lot and fights with me about it. I don't want to fight, and I've told her I'm sorry over and over and truly meant it. We're in love and get along perfectly most the time, but she tells me that part of her can't help hating me. What can she do to let go? What else can I say to her?
