Is he ever gonna call again?

I've met this guy less than a month ago, we went on a first date had sex, and met the next day too, then I was out of town for like 8 days but we would text everyday and keep in touch, I came back we still talked then he was out of town for four days, and we still talked when he came back and actually he was better than ever, telling me he wants to see me, asking me if I found anyone else etc. Then one day we had said we would meet because we would hung out at the same place with friends, and then meet, on that same day we talked and he said he would call me later (like one or 2 hours later)

well he never ever called that night, and he still hasn't contacted me since then, and its about a week, I Haven't contacted him either, but I don't get why he disappeared like that?
Is he ever gonna call again?
