How do I explain to my bf that this is why I’d rather keep to myself

So every time something’s bothering me he’ll convince me to tell him.

Literally whatever it is, even if it barley has to do with him.

Then the next time we get into a disagreement he’ll use it against me and be like “oh yeah, I’m so shitty. You always have something to say about me.” And he’ll make snarky little comments about things I’ve said that bother me.

When I tell him this is why I’d rather just keep to myself because he always throws the things I say in my face he goes “I’m not using them against you. I’m saying it as an example”

But it’s like?? Why ask me what’s wrong. To just hold onto it and then get upset at me later on and bring it up again?

I’m at my wits end. I literally feel like I can’t say or do shit.

Today I paused my tv show and was gonna go clean the cat boxes because they haven’t been cleaned in weeks and it’s starting to make me feel sick. I’m 34 weeks pregnant and since becoming pregnant he’s said he’ll take over it but then ALWAYS forgets to do it. Even if I ask him too.

So he asks me what I’m doing and I said I’m gonna go clean the cat boxes and he’s like “I can do it” and at this point I’m just over it and would rather do it myself because he’s playing his video games and I know it won’t end up getting done.

So I JOKINGLY say “no it’s okay I’ll do it, I’ll probably throw up doing it but its okay”

He then rolls his eyes, quits his game and is like “fine I’ll do it” with the biggest attitude. I literally told him I was joking and this is why I’d rather just do it myself because he always catches an attitude with everything I say.

and then he goes “I don’t care if you ask me to do it, but I hate that it always seems like you’re trying to guilt me into doing it”

Then it led to a fight where he started doing what he does lately, saying how it’s always his fault and that I can never do anything wrong and that he’s an awful boyfriend, then throwing in some things I’ve mentioned in the past that bother me and just being rude. At this point I’m upset now too and I just keep telling him to leave me alone, I’ll finish the boxes. He of course keeps going, doesnt leave me alone then after saying to please leave me alone like 10 times he goes “FINE ILL JUST LEAVE YOU ALONE FOREVER” and went back to his games.

I don’t even know what I did wrong this time. If he didn’t ask me what I was doing I would’ve left the room and cleaned the boxes without even mentioning it to him. He’s literally the one that asked!!!

He’s always taking his shit out on me. I’m 34 weeks pregnant for fucks sake. And we’re moving in 2 weeks. He’s barley helped prep for baby (getting baby stuff) and the same thing happened with all the moving stuff. I’ve had to arrange everything.

I find myself just crying when he’s not home because I don’t even know what I do anymore. Talking to him barley helps because again it’ll be used against me another time.

I just need advice, I don’t even know what advice I’m looking for. I’m overly emotional, I’m always tired, hurting, etc. and him fighting with me and taking his shit out on me really upsets me and then in turn upsets our unborn son. I love him so much but sometimes I literally don’t even want to be here anymore. Unfortunately I have no where to go as we’re at my uncles house and we’re leaving because it isn’t baby friendly. And I have no friends anymore that I can reach out too. I’m just exhausted.
