Is he interested or should I just stop caring?

Hey, never been on this sub before and went hunting for somewhere I could get advice.

Anyways, what I am wondering is if this guy could be interested of trying to string me along. We met the other night, originally for hooking up (which he seemed to be seeking most of the time on grindr). The night we were going to meet he asked if I wanted to talk first and see how things went. I had some wine, he some beer. We talked from about 10 until 1 in the morning; I'd say the conversations were fun and engaging. He then started kissing me and asked if I was OK kind of frequently. I said I was and that I was enjoying myself, but he continued to ask. Later, we undressed and started some oral, which was really great and turned to anal (as planned). He was on the larger side, which I knew, and once he got inside me, he'd continuously ask if I was OK and enjoying it. I tried to be as enthusiastic as I could, and had him feel my dick so he could see that I liked what was happening as I was hard and dripping the entire time. He then asked if I wanted to penetrate him, to which I responded, "I'm fine either way." I'm easy to please and not one to force someone to accommodate my desires. He kept asking, so I did. He was hard and I was hard, but I knew I was a bit too much for him. He kept sliding down and asking if I was enjoying myself, because I wasn't moving much because I didn't want to hurt him. A few minutes later he pulls me out and pulls off the condom. I suck him a bit more then he's asking when I'll cum, which I tell him I can go as long as he wants. Neither of us ended up cumming which I didn't understand. He wanted to rinse and asked if I wanted to do it alone. I don't get what to make of this and it's stressing me out. I sent him some thank you texts explaining how much fun I had. He replies with, "Are you going to be disappearing on me?" I don't even understand how he thought that. The whole time I was with him I was saying how I loved everything. Now since it's been a couple days he changed his profile on grindr to a face picture, continues to send very short texts and hasn't replied when I was saying Goodnight and checking in. Does anyone do similar things and what should I make of this situation?
