The woman I had been dating broke things off after her live-in boyfriend became uncomfortable with her dating around. I had fallen for her pretty hard, but didn't want to strain her primary relationship, so I let it go. We've remained friends--good friends, even. I think I know her better now than I did when we were dating, and we still talk nearly every day. I wish things had turned out differently, and I'm sometimes sad that they didn't...but having her in my life as a friend is a lot better than nothing at all.
