Marriage is all about respect and communicating that respect through words and actions. It doesn't sound like much of that is happening. Counseling would be a great way to start an open, real conversation.
Your job is not just to work and follow a to do list from your wife. Her job is not just to clean house, prepare meals and raise her child. Those are necessary functions to be performed, but have little to do with a real marriage.
You desperately need some open, heartfelt communication between the two of you. It is difficult because you both feel wounded by the actions of the other. You need a mediator, a neutral third party who has no emotional investment in either side of the marriage.
I know it is expensive and difficult to arrange, but it sounds like your marriage is slowly withering. If your child was dying from a painful disease, would you worry about the money or difficulties involved in finding the needed treatment? If you want to SAVE your marriage, you are going to give it the same effort.
I wish you and your wife the very best. Just don't let your marriage die without exploring every treatment option with a professional counselor.
