<human>: Provide a brief overview of the text.

I met this guy on tinder (I know, I know), but immediately knew he was different because he didn't bring up sex and would have long conversations with me about whatever randomness I wanted to discuss. Anyway, he had gotten out of a one year relationship only about 3 months prior. 

We started hanging out and hooked up some, but waited tip we had known each other a month to have sex. He would ask, but respect me each time I said no and drop it. When we finally did have sex, I initiated it and he kissed me so passionately I was in awe for a second. 

Normally, after our other hookups we'd cuddle for a few minutes, do i again then put our clothes on and he'd walk me out. I'd text him when I wanted to talk to him in the next couple days or so. But after sex we just laid there and he talked my ear off for 2 hours. Then he just kinda rolled over like he was going to sleep. I told him I was going to go, as I had a class at 9:40 the next morning. He asked me what time it was, I said "11:45." He asked me to stay 15 more minutes, so I did. 

The next morning he texted me all freakin' day starting at 8 AM. We're currently on a fifty-day snapchat streak. We talk a lot and he NEVER brings up sex. He won't invite me over after a certain time because, and I quote, "We won't get to spend enough time together." He keeps coming up with reasons to see me, but he never wants to go upstairs and I don't push. Recently found out I'm the second girl he's had sex with, the first being his long term girlfriend. 

I just don't understand the behavior change, but I would like to. I've wanted to discuss it with him, but it's not a conversation I want to have over text and when I see him in person now we're in fairly public places. My opinion is he wasn't actually ready for sex but did it anyway and is now confused.
<bot>: had sex with a guy, then his behavior completely changed. I have an idea of why but I wanted some feedback.
