SHOULD I TAKE HIM BACK‼️⁉️

My bf and I have been together for a good while, now that I have moved away to university things have been distant, he doesn’t really txt me as exciting as before, he doesn’t really want to video call with me, only like once in a while. He speaks to me in some ways I don’t like and I’ve always told him to stop it, he normally stops sometimes but then he does it again. We broke up 3 months ago but now he continually texts me and says that he is going to change and stop talking to me certain ways I don’t like, he says things are gonna be different n that he is sorry for everything. I don’t know if I should take him back.
