About four years ago, I developed a crush on a coworker. She was perfect to me in every way. She was seeing someone, so we were just good friends. Ten months later, she broke up with her SO and moved back home, five hours away. Another seven months passed, and I missed her so much, that I visited her on her birthday and we ended up having sex. It was the best I have ever had.
After that, we (she) decided we were better off friends. Since then I’ve gotten into a serious relationship and it’s been two years. I love my girlfriend very much and am very happy, but I still think about my coworker, and that night, and I can’t get over those feelings.
We don’t really talk anymore, but I still somehow can’t get over her, even though its been over three years. What do I do?
