AGONY: I am sexually starved and confused

RELATIONSHIPS & DATING

I have always known women to be possessive of their husbands, but mine confuses me. When we have a disagreement or when she wants me to do something, she denies me sex, until it is done. 

Sometimes, she asks for things that need money or dealing with other people whose reaction I am not in control of, but she still takes me through that. 

I have tried to explain my feelings and her response is: "Go to the maid to relieve your urge." 

We have a hardworking maid who takes care of our children and the home. Has she lost interest in sex with me, to the extent that she does not care if I slept with the maid? 

Does she have a lover, so she wants to trap me into another relationship? What is her intention of doing this? She has done it for over two years now. I am starved and confused.
