Ughhh ... I met this guy and we hooked up once. It's been like 2 &1/2 months now. Since then .....?

... I have seen him twice (hanging with mutual friends) & it has been totally platonic. I really, really felt a connection with him. He is a super nice guy but just went thru a divorce. So I have backed off & gave him his space. ProbIem is I can't stop thinking about him ... i think about him like every day. I haven't felt like this about anybody in a while. I think he may like me but then it may have just been a hook up for him. I want to pursue something with him but am afraid that its too soon for him, or that he may not feel the same. But then what if he does? I've been dating other guys recently but none of them make me feel like that. I just keep thinking of him. I've been trying to just push my feelings aside & see what happens in the future but it doesn't seem to be working. Is a hook up just a hook up and am I being silly to think of it as more? It felt like there was an emotional connection. Too naive? Should I just talk to him about my feelings? If so what should i say? HELP
