Before he told me he liked me we talked/hung out a lot, now we don't so much?

Before my friend told me he liked me we used to speak and hang out every day, even after classes (by facebook or text). Now that he told me he likes and I told him I like him back... he's suddenly not talking to me as much any more, we're only talking between class breaks, he even seems kinda reluctant to hang out with me at times.

I'm so confused? Why is he being like this now?
