About 4.5 years ago, I (35m) went on a date with a guy (32m) that went great. Really good conversation, lots in common, and I could feel a major spark. Only problem was I had just gotten out of a 3.5-year relationship (like a week before the date) and was still needing a lot time to process that before I was ready for anything serious. He asked when we could hang out again, and I was going out of town that weekend so I said we could hang when I got back. He pulled the old, "You're gonna make me wait a week to see you again?" I relented and agreed to a second date that week, which also went great. I remember he went out of his way to call me when I was out of town just to chat, and when I got back in town, things took off. We were hanging out a few times a week, sleeping at each other's places a lot, having sex, meeting each other's friends, etc., and it was great. Even gave me a key to his place. (He was in residency and would have to get up at like 4:30am, so on...
