Guy Problems

So I just got out of a relationship that lasted 2 years and there is this guy that kinda was like an emotional rebound for me I guess. We would make out and get flirty but every time he would start going a little to far I would tell him to pretty much stop, but the last time this happened he asked me when we were going to take this thing seriously. FYI he doesn't really care about me because all he wants is the sex so I don't really know what to do. I don't want to have sex with him though....should I not see him anymore?
