If your wife gives you a hard time about working from home, or being a stay-at-home dad, it's a strong possibility that the two of you are not going to be married 1-3 years from now. That's the ultimate sign of disrespect and if it continues, you may as well start interviewing qualified divorce lawyers.
I know from experience that regardless of what the situation may be, if a married couple are not on the same page and do not mutually respect one another in all areas, stick a fork in the marriage, because it's DONE!
