Am I over reacting?!

After talking to the guy I was seeing for a couple of months we slept together sex really wasn't as good as I expected he was basically all talk. Well after we did the next couple of days he hardly talked to me or replied and I KNOW he wasn't busy because he'd send me snapchats of food or a movie he was watching so I was just like fuck it and I texted him and told him I wasn't going to be seeing him anymore he asked me why and I just explained that he hasn't really been talking to me and he replied "well if that's what you really want to do?" And today I was thinking like maybe I was over reacting or thinking into it too much. What do y'all think? Am I over reacting or does it seem like he just wasn't that interested?
