Am I in the wrong?

Boyfriend and I got into a conversation on Friday because he kinda treats me bad and I brought up my concerns and how to fix them and tbh I just really didn’t want to be in the relationship anymore but he manipulated his way into it again. Then on Saturday he asked to hang out and I said “Maybe i’m not sure yet if I’m ready to hang out” and he said okay and i said but if you really want to we can. And he said he did and I said okay we can. But tbh I didn’t really want to but i hate cancelling and saying no to people. idk why. anyway I get there and i get into the car and i’m just not myself. And I said hey I know you really wanted to hang out but I don’t really want to, I don’t feel myself, and I just felt bad saying no to you. And he started to call me disrespectful and get really upset with me. He told me to get the F out of his car and I said why can’t we talk about why youre upset? and he said he didn’t want to talk to me anymore. And I don’t like leaving on bad terms and i said “You don’t care if we leave on bad terms?” and he said No I don’t care. I then got up and left his car. Now we haven’t talked all day. Was what I said rude? I feel bad but also I didn’t realize that it was that mean
