Hi OP, you're getting a hard time on here so I wanted to say: I had an abusive, narc dad. I can understand why you can't speak to your partner and resort to messages - because he's completely incapable of any sort of reasonable discussion, as he sees everything as an 'attack'. If you've never lived with someone like this it's hard to comprehend, but I do get it. Completely.
My dad would also accuse all of us - me, my mum, my brother, my uncles, anyone really - of doing the things that HE did. So we were abusive, we were narcs, we were 'screaming' at him, we were unreasonable, hysterical, out to attack him etc etc
We were none of those things. Ever.
But being in a relationship with someone like that sends you a bit mad. You question reality. The gaslighting works so well, that you think - oh, maybe it IS me.
And you stay in an abusive relationship trying all sorts of frankly batshit things (like texting rather than talking) because you believe them when they say - it's YOUR fault, YOU'RE the one with the problem.
OP, get out. It will only get worse. You cannot reason with someone who is unreasonable.
And please, please ignore the trolls on this thread who are clearly in the same league as your partner. They're really not worth the headspace.
