You need to change something. Other people have better advice, or at least specifics due to personal experience. But I can see that you are living in resentment and hell. There is no way your relationship with your wife is healthy. You've got a kid right? That child is watching you two and learning what it means to be in a relationship. They pick up on stuff left unsaid, you aren't hiding anything successfully (if you are indeed trying to hide these feelings).

Would you want your child to grow up to feel the way you do now? You're giving them the lesson plan right now.
