AITA for refusing to do anything around the house because my wife insisted on staying home with our child

I(28m) have been with my wife (27f) for 4 years married for 1. I’m an electrician and she is an accountant, I make about 60k a year and she makes about 55k. 7 months ago we had our first child, my wife was supposed to go back to work 2 months ago (she took the maximum maternity leave her company allows, 6 months which she started 1 month before labor).

When it was time to resume work my wife told me that she would feel guilt and sadness if we put our child in day care, therefore, she wants to stay home with him. I suggested therapy but she is very persistent and says nothing a therapist would say will change her feelings. At this point it seemed like I had no choice so I started calculating how much I would have to work to compensate her income, I usually work 45 hours a week (9×5) and without her income it would have to be at least 65_70 (9_10×7) 10 hours a day EVERYDAY of the weak, I told my wife how greulling it would be and she tried convincing me by saying I must sacrifice for our child and she would do all the child care and house work and I wouldn’t have to do anything around the house, even without any housework it is still very extreme but I reluctantly agreed because I felt like I had no choice.

So it happened, my wife resigned from her job (company policy, if you don’t comeback you get replaced) and I picked up the extra hours, my day starts by going to the gym at 5 am (it is the only thing keeping me sane) and then I would work from 7_5 and get home at 5:30 absolutely spent and I just want to take a shower and rest.

During the first month or so my wife kept her word and took care of all the house work but then she started expecting me to help her around the house but I would remind her of our agreement and she would look annoyed but move on and do it herself. 2 days ago she told that she is tired and wants me to make dinner and I flat out refused and told her she is breaking her promise and I made it very clear that she shouldn’t expect ANYTHING from me when it come to house work. She looked furious but she got up and made dinner and since then she has been giving me the silence treatment. I’m full of anger and resentment right now at first she got me taking 25 more hours a week and now she is breaking her promise and trying to manipulate me by giving the silent treatment, I’m losing my mind.
