Rant ( Please help me ladies )

We had a great morning ya know. We didn't fight at all...until I said

"I really don't want to move with your mother" now a little background on his mom. She's a sweet kind woman that is always giving. But the moment someone says "I'm tired. I'm stressed. God I need a vacation" she says "not as bad as me! You can't even say your stressed." Like a mom talking to her child about them being stressed. She's pretty snobbish and she makes this face sometimes that seems uppity and makes extra comments that shouldn't have been said.

Well then he says 

"Well what choice do YOU have?" And I said "I was just sayin-" from this point on he constantly cuts me off, not letting me get a word in. He just started going on about how I should speak to her about how I feel and how I don't want to be spoken for and I Need to make a decision. I came at him calm trying to see if I should feel this way. I said something because before we had to leave, he said something about him being tired, and she said "You can't even say that. Not as tired as me. All this money I had to put out for this bed bug situation." And it pissed me off. We're all having money issues, we're all getting bit by bedbugs, we're all suffering from being crowded (we sleep in the living room). And she always seems to emphasize how it's not her fault the bed bugs are here.  So I am highly pissed about it. So I kind of shut down because i was confused as to how I deserved to be talked to like that. And the second incident is last night, where my bf came home and our daughter was trying to sleep beside me. She was irritated because it turns out she has an ear infection in both ears. So she didn't sleep all night. But before my bf came home, for 30 minutes I have been trying to console her and comfort her thinking she was just sleepy. When he finally got home and came to lay down, she was still irritated and I was tired and stressed because she was well fed, had nursed, changed diaper, warm clothes, everything. So she was crying and all I could do was stare angrily because I was so irritated and tired and I couldnt even conjure a thought; my mind was blank. I was just angry. (Not the "I want to hurt you" angry) and he said:

"Why are you staring at her like that?" I just responded "what are you talking about"

And he said "you wanted a child, you take care of her" (a little background. When I got pregnant with his baby, he did want an abortion initially, but I felt I could do it. But he loves his daughter)

I tried to explain to him how tired I was and he said "Don't bullshit me bruh. I swear to god bruh."

As I continued trying to explain, he said "say something else..." I was silent after that. I woke up in the morning around 6:00, went in the bathroom to smoke a J (idc if you agree with it or not, I'm growing gray hairs from stress. Leave me alone about it) and I came back to him and said "if you ever threaten me again, you'll be single." And he said "threaten you?" And I said "yeah" and he was confused so I went and explained it to him and he said "yeah cause you got me fucked up. I know what it looks like when someone is getting tired of someone." I was like "but--" then he said "stop talking to me bruh." Then I tried again and he continued to say "stop talking to me". I'm not sure how to feel. I was following directions, respecting him, not coming at him sideways either situation. Someone help. Wtf happened?
