Am I doing something wrong or does he have unresolved trauma?

the longer we stayed in the rent together the further apart we came. He had developed this tendency of being very verbally abusive. He had ways of being manipulative or gaslighting. He had developed ways of in our conversation being very critical, or in other was saying things are that are mean but then being defensive saying that they're only jokes. He would not talk about problems that he feels that are not addressed. But down the line he says that he has no animosity towards me, which makes me very confused. I don't know where he secluded himself in his bedroom and told me that the entire apartment is now mine? He does not help at all with any of the cleaning, he forgets to take the trash out, he doesn't sweep, the sink is full. I tried to clean as much as possible while being a full-time student but he only tends to just utilize the things I clean but doesn't pick up after himself. He jokes around about the maid not doing the job. Even though in the beginning of the relationship I said I'm not going to be anyone's mother. And then sometimes when we do talk he usually flaunts about his day of how great it is and then never asks about how I'm doing. And when he helps other people he flaunts about it. And when I do not express happily towards anything he talks to me about he then gets verbally negative and critical towards me for no reason. When in all honesty he only talks about himself all day. He generally never seems to be interested in what I say. I'm just generally dealing with somebody who used to be someone I wanted to be with to somebody who's always verbally negative towards me, never wants to hang out, leaves a mess in the house, only comes home to sleep, secludes himself in his bedroom, I'm the one who takes care of all his pets, and he jokes about me doing all the chores. It's pretty baffling that when he does want to be genuine is when he needs to borrow money from me or he's in a predicament that needs my help.
