9:12 p.m. He calls. "Yes, come over!"
11:30 p.m. After a night out with the girls, arrive at B.'s. He's asleep. I'm starting to fall for him, but he's never been a fan of commitment. Get in bed.
12:20 p.m. At B.'s, who's hanging with his best friend. Friend makes comments about my breasts. Roll my eyes at B. He sort of smiles back. Something's wrong.
2:30 p.m. "What's going on?" I ask. "Do you want me to leave?" He shakes his head. Turns out, B. needs to have leg surgery. It's official: I'm self-absorbed.

12:00 a.m. At B.'s, we have sex. After, I say, "I'm freaking out. My feelings are involved in this." He bangs his fist against the headboard. "We need to have this conversation," he says. "But I can't do it right now. Good night."
2:00 p.m. B. has a small party. He's talking to a gorgeous girl. Decide he is dating her. Pack suitcase and leave.
