pranky

Ok, this is awkward. I've liked him ever since I joined college, from day one, and he's always treated me different, always looked out for me, done favors etc, everyone tells me he likes me and I feel so too.

He has had a rough phase in his life where he lost his mother and recently got divorced. We started talking through Facebook a couple weeks back and he asked for my number. We are constantly in touch. Then we had a bet on something and I had to take him to lunch/dinner. But since he is very well known around, he said it would be better if I went to his place and I did. Nothing funny happened, we just talked. And when I left, he kinda hugged me. He texted me later saying he had a really great time and we should do this more often. There is no future to this but I can't help myself.

He's 40 and I'm 21.

What should I do?
