Why?

I'm never right, even when I know what I'm talking about and he doesn't, even when the facts are screaming that I was right all along. My opinions aren't worth asking about, much less considering. What I think is wrong, and I should change it. His dream is the one we should share, uncompromised. My experiences and thoughts, my daydreams and feelings, are all inconsequential. My desires are inconvienent at best, stupid at worst.
He only wants me when he's been looking at porn before I showed up. I never turn him down, I can't recall a time in months where I haven't had to talk him into having sex with me.
He's rude to my friends, or just stays out of the room I'm in with them all together.
Why would I leave? Why would I stay.
