Blows my mind

So we had another “I’m not getting any sex” conversation talk lol he basically told me that if sex stops in a relationship and I decide I can’t do it anymore then I’m cold hearted. He doesn’t even want to try, has no desire and just doesn’t want to. His words. He doesn’t know why. Swears it’s not the relationship or desire for me but refuses to work on it. I told him it’s unfair for me to have a sexless life because that’s what he chooses for himself. He says I’m selfish that I’d just abandon him. Then he compares it to someone having an accident and being paralyzed and unable to have sex. I’m like bro, that is not the same thing. He says if you’re in love and committed you should say together even if there’s no sex. I disagree.
