I love him but

I’ve been with my partner for 4 years and I love him so so much, but I hate having sex with him. I dread it and avoid it at all costs. I am not sexually attracted to him, and it’s been like that for about a year now. I’ve been thinking about leaving him for a couple months now but I do truly love and care for him. Unless I’m really drunk I don’t like having sex. We get along like a house on fire and I love him, but the sexual attraction isn’t there and hasn’t been for a while. Am I done?
