Why would he suddenly stop taking initiative?

missann
I have been talking to this guy for quite some time. Most of the time he would take the initiative to call or text me. Sometimes when I didn't hear from him, I will take the initiative. Somehow he had completely stop taking the initiative to talk to me. I am not sure if he was busy, he told me he was but I happen to see his FB and it was active.

I wonder what happen?
