My wife is a SAHM too, and boy I wish we didn't go down that route. We were lucky to be able to afford it, but she never liked it. Then I would feel that she was ungrateful. I felt like I was working all the time, and then I would come home and the house would be a mess and nothing got done. I felt like I was being used. I really regret these feelings now, because I am sure these feelings lead to her resentment. I love her so much, but I am scared her resentment will never leave her now. I am scared that I will have this regret and guilt the rest of my life. I am so scared that I will never be happy again.
