My SO said they're sick, I told them to go get checked, they said they didn't want to, then I said "okay" this is all through text

Then my SO said something like "ok well I'm going to sleep you don't wanna talk anyway" and it confused me? So I called and said it hurt my feelings and I started to cry and my SO said "no you hurt my feelings" so I'm sitting here crying on the phone and my SO starts to raise their voice so I said "you're really mean" and hang up, I then call back crying and my SO just basically turns the entire situation around and makes it about me hurting their feelings. I ask them on the phone if they're going to be here for me because I'm scared and I'm crying..? And they said they just want to go to sleep.

My SO used to be there for me.. used to be sweet when I would cry.. now I find myself crying alone without them to comfort me. My SO says it's unfair to have to comfort me if they're feelings are hurt too. But the thing is.. every time I say they hurt my feelings, I magically have hurt theirs too? My SO threatened to block my number if I ever hang up on the again.

I don't get it. She was never like this before. I'm so scared. Even more so because I'm supposed to be moving to another state for this person and this is freaking me out because now they're this person... and they always tell me I'm in the wrong and that their feelings are hurt and not mine but I find myself crying alone at night a lot of the times.
