<human>: SO and I (27/f) have been together over 6 years. At a point, there was a perceived break in trust, although I never did anything (emotional or physical) and the thought of that with the alleged "other" disgusts me to this day.

Ever since then, in the course of our relationship SO has construed it as if I "owe" him things- house work, dinner, favors, sexual favors, etc. Whenever I bring up my needs, I'm told that I should be grateful that he is with me, that he has supported me financially, and that I'm being ungrateful.

When I take a stand on something like my not receiving the sexual fulfillment that I desire, or he not contributing to chores, I am ignored. If he asks for something and I refuse or ignore, I'm the worst person on the planet. 

I try to talk to him and he blocks me out. I'm always left feeling as if I did something wrong, even though I know I didn't, and it is always me who initiates any kind of "make up". I've been at my wits end about it lately because we are both under a lot of stress, but I'm not sure I can handle this for forever. The rest of our life is pretty great- even though he isn't terribly affectionate, sex is frequent, and we do lots of activities together. 

How do I address this? Is there something that I am doing wrong? Is there something I can do to make him listen? Despite this, I do love him, and the thought of splitting makes me sick.

Can you condense the text into three sentences or less?
<bot>: SO makes me feel like I "owe" him, makes me feel like I am always in the wrong, and never listens when I try to talk to him about it.
