Is this normal??

There is this guy in my college, we have been pretty close for a year. He is an amazing person, humble and sweet, we have been there for each other during hard times, laughed and cried together.

Yesterday for the first time we got physical, it was something really pure for me, the feelings we had for each other and it was not lust.

After we were done, he just dressed up and left without talking much, asked him to text once he reached home, but he didn't.Waitedf for 2 hours and cried myself to sleep.

I have been texting and calling him since morning he isn't picking up. I have been crying for 3 hours now.
