Why did he bother to explain himself to me?

Si I’ve been chatting with him for some time.

This last time when we chatted I noticed that something was off. His replies were shorter, he wasn’t as playful as before etc. His responses were slow to too.

It bothered me so much that I left him on read for 2 days and then replied to his text.

then after that he sent me a long text explaining why he hasn’t been responding to my text like he was before (he had really good reason. He was basically on a hiking trip with his boys and he couldn’t use his phone like before).

Does that shows that he cares and he doesn’t want to upset me? Is he catching feelings?
