<human>: Can you provide a brief rundown of the text in within 3 sentences?

I've known this guy for about 9 months, and ever since then we have hooked up every few weeks or so. We live in the same town, and are both seniors but at different high schools so we rarely see each other.

From the very beginning we both made it clear that we weren't looking for a relationship, but did enjoy each other's company and having fantastic sex. 

Anyways, in between the times we hooked up, we talked very little. He would call me or I him and we'd fuck and not hear from each-other for a week or two. 

The last time we had sex was about a month ago, and it was especially good. He called me a few nights ago and just wanted to talk- and we did for about 4 hours. About everything, we really just click. But we already knew this. He has called me every night since and has been texting me during the day-VERY out of the ordinary. He even asked to take me to prom.

I enjoy hearing from him but I can't help but think that something is up? We both will be going to college soon so I think a relationship is out of the question, but I also don't want to hurt his feelings because as he has told me before that he cannot handle rejection. 

What do you guys think is happening and how should I handle it?
<bot>: FWB is acting like he wants to date/clingy, and I don't know how to breach the subject without hurting him or embarrassing myself. Help?
