Familiarity breeds contempt - so after about 2 years wives tend to feel contempt for their husbands. Its normal and unavoidable that a woman will feel that she could have done better and even if you have both read ‘Men are from Mars and Women are from Venus’ women will judge men by female standards and the men will be found lacking.
However what men need to avoid is resentment. It is a negative and corrosive emotion and is not good for your wellbeing. For me fucking other women seems to be quite effective at reducing resentment. Plus if you are going to get in trouble for the little things like leaving your socks on the floor rather than putting them in the dirty clothes basket (even though you intended to wear them a bit more) you may as well get in trouble for something enjoyable. Life it too short to waste on negativity or miss out by being a martyr.
