Hahaha - reminds me of the first guy I dated after my ex left. He lived an 11 hour drive away. We chatted online every day. When I finally went up to visit him it was fireworks. BUT - he had a "three day rule". I couldn't stay more than three days.
Usually that wasn't an issue, but one time I went to visit and his adult son needed some medical attention from me. The son and I hadn't been able to coordinate our schedules to get together, and on the third day I suggested that I could stay an additional day in order to meet up with his son.
He ROLLED HIS EYES at me! Like it was some huge imposition! Mind you, we had been dating for many months at this time.
I left his restaurant, packed my things, and left him a note. No way was I sticking around with a guy who was upset that I might stay an extra day, to do a favor for HIS son!!!
(End of story - after a couple of months we did reconcile, and I saw him a couple more times - but then his old childhood sweetheart turned up and I was toast. They are still together several years later so I don't feel too bad about it.)
But what I learned since is that he is a classic Love Avoidant. Being too close makes him anxious (hence he could only handle it for three days lol). He was fine and comfortable with the long distance thing because it didn't crowd him too much. But Avoidants fear being controlled or smothered.
I dated a few others like that. And I had a friend once who was also an avoidant - he explained something to me one day when I was asking him about his dating habits. He said if he made an appointment on Monday for a date on Friday, it "hung over his head like a dentist appointment". Therefore, he would wait until the last minute to ask a woman out; if she had plans, it was no big deal, he'd catch her another time, but at least he hadn't spent the whole week with a date hanging over his head!
Now, I don't know for sure if your guy is a Love Avoidant. But you might want to take a look at his dating history to see if there are signs.
Otherwise, he just might have other issues. Extreme introvert who doesn't get enough time alone when staying with you? Closet alcoholic who can't go that long without drinking? Closet smoker who can't go that long without smoking? Bad OCD that gets triggered and he can't control it past a couple of days?
