I want to completely cut my friend/housemate out of my life because I think he’s a narcissist and being emotionally abusive to me.

I’ve known him almost 10 years, i’ve always known him as a little quirky but never anything particularly malicious, about a year ago we moved in together due to personal circumstances. But since we moved in together i’ve realised something’s just… off.

Some bizarre things, like he often brings up subjects to me that make me think he doesn’t really care about anyone but himself. He fairly regularly brings up how he can’t understand that other people have the same level of thoughts as him or that he has certain friendship groups that he likes because they’re less attractive or smart as him so they make him feel good.

I also feel like he’s slowly trying to chip away at my self-esteem, he always drop oddly negative comments into conversation, about the strangest of things like my appearance, my job and work ethic, even the TV shows I watch - this recently escalated to him calling me ‘a heartless person’ and ‘a horrible friend’ for no reason at all, he just dropped it into conversation like it was nothing - I tried to bring this up to him and say it’s not okay but he seemed to just refuse to acknowledge it even happened, he asked for specific dates and times when he called me these things and wouldn’t even talk to me until I did. After a while he started listing reasons why he did what he did and then just told me I was overreacting.

This isn’t the first time we’ve had a disagreement but i’ve realised now that he does this every time I bring up an issue to him - even stupid things like “it’s your time to vacuum” - he denies it, asks for evidence, tells me why i’m wrong and then says i’m overreacting, sometimes he’ll even bring it up a few days later and say something like he “spoke to one of his friends about it and they agreed with him.”

WIBTA if I just leave and cut contact? I feel like whatever is going on it’s going to end in my self esteem and mental health being ruined and I don’t know what else to do. Every time I tried to approach my issue it always ends the same way. I’m worried that if I do this I might lose other mutual friends.
