<human>: Condense the text into a few key points

Guy I am seeing and I just had the exclusive talk, but prematurely. We had to have the talk because we got into a heated discussion (definitely not a fight) about another issue and I thought he wanted more, so I wanted to clear the air. 

We talked and we both like each other but don't feel close enough to be in a relationship with each other, but while I want to date him exclusively (but not have the pressure of a relationship just yet), he does not think that step is real because he feels like if he wanted to date exclusively it would be a relationship. Fair enough. But now I'm feeling insecure (worst feeling ever) that he still wants to date other people (maybe?). I haven't dated anyone else and he hasn't either, for now anyways. But he is still on dating websites and using them regularly.

Prior to the talk, we have been texting everyday, mostly prompted by him and we try to hang out at least once a week, but we are both super busy. After our talk, he is taking longer and longer to respond, but has told me he does not want space away from me and I should text him if I want to. I am 100% confident that if I do text him, he will respond though.

So the question is, what should I do? Do I pull back and ignore him for a while to see if he pulls forward? Do I date other people while he thinks about he wants? Do I act like nothing has happened and hope my insecurities don't get the better of me?
<bot>: Guy I am casually seeing does not believe in being "exclusive" before being in a relationship. I thought I was fine with that, but now am feeling insecure he might still be dating other people. What do?
