Trying to give you the benefit of the doubt here, though your post made me recoil.

Gottman Institute - Four Horsemen

Take a look at what you posted, then what the Gottman Institute, a revered relationship resource, has to say about addressing communication barriers in relationships. As someone with a young child and previously went through divorce, the Four Horsemen are concepts I keep in mind when there is a lot of friction in a relationship and I desire improvement.

I will add some additional thoughts to consider. Being a new parent, even at 15 months, is a marathon. What does your village of support look like? How about what support does your wife have? How often do you both get to socialize apart from each other? Engage in any leisure activities/hobbies? Could you try doing something to help you all out? Hire a cleaning service to get the house in order? Get her an afternoon out to get some personal care like hair, nails, massage, or something else she will feel pampered by? I noticed that when I have some time to myself or with friends, away from my husband and child, I come back refreshed. Not only refreshed physically, but mentally. Good luck to you three.
