Bad words

I'm a very sensitive person and my partner and I argue a lot. And he asked me 3 days to look for his notebook(that was mine and he just wrote over it) and I get that he liked it because it was small and he uses it to play his video games. Whenever he asks me its when I'm with the baby or I'm cleaning, cooking or running errands. I have to get out of the habit of saying ok and getting distracted and forgetting.(this has been going on my while life). So he got frustrated asking me once again for the notebook and he was angry and me being sensitive I just asked to not be rude to me about it and he said he cared about that notebook and it seems like I don't care and f it and f that. He said he will look for it himself and f me too . I just went into the room and the notebook was somewhere in the room. He got it and went back to his game. I came out and let him know he shouldn't talk to me that way . That he can be angry and frustrated with me but to not talk to me that way. He kept playing and said, ok. Then he said . Well what about you and what you did was wrong and you don't care about what was important to me. I take care of him and our son. He barley cleans, cooks and I give him space and tries to tell me I don't care ? So I let him know again that he can be mad or frustrated with me but it seems like he has no respect for me. And he's not even sorry about it. He says sorry, I'm right but in a serious tone and I tell him that he's saying that just because I made that statement and he kept trying to tell me the same thing about the notebook. And at that point I just stopped but he again said I was right and hes sorry. And I just said ok and went to the room because I am upset. And I can hear him say. Really ? Wow. Like I'm just so wrong for walking away.
