Why hasn't he called back after a fight

i just had a small minor fight with this guy that I like, I text later to say listen I'm jus stressed because I don't know how to deal with this siutation of liking u, its not ur fault, its something I have to deal with" btw he says he doesn't like me (his behaviour is contradictory though), but I'm going to accept what he tells me. He hasn't replied to the text...My answer to the guys has he not replied because:

1) he doesn't give a shit, thinks its not his problem, she needs to deal with it.

2)Doesnt want to hurt my feelings, doesn't know what to say so is staying silent.

I thought my text was mature, non emotional and so I thought he would reply back with something supportive like its ok etc...or am asking too much of a guy?

Please respond guys!
