I started dating my best friend, and the best person I know, last fall. We'd known each other for years, I got drunk and kissed her, it turned out she'd felt the same way for a long time. Over the next semester both of us spiraled into semi-depressive episodes (her for gender problems in her field, me for weird social reasons) It got to be less fun to see each other, more routine than relationship. All the life we'd had for us disappeared, week after week we were looking more for each other to fix problems, spending time together got miserable. We were in bed one night. I turned to her and asked when we'd stopped being friends. Neither of us knew. She broke things off a few days later.
