Hispanic men by and large have expectations that their wives dote on them. In return, Hispanic men tend to be big family men - on Sunday afternoons, instead of hanging out with their guy friends or mowing the lawn, they tend to prefer big family gatherings. All the kids running around, the women together and the men together. All together, all affectionate.
(Doesn't always work that way, that's the ideal.)
They tend to want to be the caretakers, and earn the money and take care of their family and don't go "halves" usually with winning the bread. They are the head, and they take care of business. In return they want their wives there when they come home - with a big smile on their face and food on the stove.

Until you are on your own, you will likely be expected to do much around the house as a form of rent (even if you are paying her something) and your mother in law will be in your business.
If he is not willing to give you room to be your own person, won't negotiate and won't go to counseling, then maybe this is not the right man for you.
