my boyfriend is schizophrenic and thinks im a liar and secretly against him all the time. we just had a fight because of this:

i asked him to call, and i told him i might play and stream my game over discord
he said he doesnt want to watch that game. he also seemed generally annoyed and was writing harshly out of nowhere, so i took it as him not wanting to talk right now.
i said 'tell me if u do want to call'
i went to watch videos in bed.
then he wrote me a bit later 'ure not even playing' and went on about how i should just tell him i dont wanna talk to him and got angry with me and said he doesnt want to talk anymore

i realized afterwards he literally thought i lied about playing this game he doesnt want to watch, so i dont have to call with him? when i was just considering playing, and then lost my motivation to get up so i just watched stuff in bed?

so we just fight over something so ridiculous, because i was just assuming he is annoyed and doesnt want to talk, but then he comes out and accuses me of lying and i feel like i did something wrong

and i dont really know how to cope with it. i know why it happens but i have really bad anxiety and that stuff triggers it pretty hard (fear of messing up ykyk, no fun) idk, maybe theres some way of handling it better, bc i just go full mental breakdown and that obviously doesnt help anyone
