If a person says they have a crush on me, but they have never called me in the last week, what am I to think?

now, maybe im just being a little too weirded out... but the person i am referring to.. we had a date where i thought things were going well for the both of us. this person admitted he has liked me for the last 3 months, but has never had the guts to tell me. Somehow he worked up the courage to ask me cuz I ended up going out with him. Most of the things he felt for me, he basically let it all out. I responded to him that I felt the same way, and I thought from that point on, we were going to be "A Happily Ever type couple".

Now one week after that date, I never heard anything from him. This is after I have at least texted him a couple messages and tried to call him on his fone. Im just wondering, was this all just a game he was playing?
