I don't feel like there's enough information about anything or anyone in this scenario, and I don't trust the complete ambiguity of this post tbh. Your use of "apparently" implies an abject cluelessness to why he would be complaining about such things. Could he have said "you don't get it" because you may be unwilling to reflect on how you act towards others? Did anything happen to lead up to this? Were you nothing but kind to the people around you, only to hear this anyways? If I were you, I would try to sit down and have an honest conversation with him about how the both of you could try and improve your communication, and I'd try and reflect on myself and think of ways in which I may have hurt others in the past. If he really is just pulling these complaints out of his ass to make you feel bad, and if there are signs he could be controlling you, then yeah, obviously that isn't good and you deserve better. But something about this post... doesn't sound right to me. I don't really know whether this is just an unfounded attack on your character or a lack of self-awareness. It's not wrong to swear a lot, but criticisms for being aggressive and controlling are definitely not something that should be written off if they have any basis in reality. I am sorry for the confrontational tone, I really just want to help.
