Why doesn't a man write for a long time after a resentment?

Normally, my friend and I used to talk every hour, then we stopped talking because of my fault, because it coincided with my bad period and I was always exploding my anger towards my family and people around him, but in this last fight, he didn't take it anymore and said let's take a break from talking, so I said okay, he hasn't written for a week, how can we be the same again, or will we text again?
I don't speak much English, sorry if I made any mistakes.
