Honey, I'm not sure I understand this post. From what I gather, he uses you to make jokes; He says HE'S the boss and that's that; he doesn't want to have sex with you; and he's cheated twice and won't admit to it. Is this right?
From the sounds of things, it sounds like you two do a lot of fighting!! And if you have children, that's no place to bring up kids! I grew up in a home where my parents were fighting all the time, and it had a terrible effect on me! Of course they were drunk too, and that didn't help.
Do you think that marriage counseling would help? Would you two agree to go? Counseling CAN help if both parties are willing to go. If you BOTH are willing, give it a try. If you are NOT willing, then I don't see much hope for the marriage at this point. You should at least give it a try, so you can say that you did all you could. I wish you the very best. God bless and take care. Hugs, Lee
