Whats the easiest way to slow things down?

Okay, so I met this boy sunday, he was nice I got on with him with ease, we swapped fb names and numbers. He said he liked me and I told him too, he had a gf at the time, but said it wasn't working out, yesterday I find out he dumped his gf, (I was shocked!), and he keeps telling me he's falling for me and loves me. I don't know what to do, I didn't want him to dump his gf, because it seems like it was for me. I like him, but I don't know where this is going to go, and I don't want to push him away, as I like him and for once someone likes me back. What should I do, I've said I don't want to rush into things, but it seems like it's gone over his head. HELP PLEASE?
