While infidelity has traditionally been regarded as a masculine trait, an increasing number of women are cheating on their husbands. Financial equality plus more time spent at work are fueling this role reversal.
It wasn't so long ago that women would have felt obliged to stick at an ailing marriage, these days they don't feel so compelled to stay.
A surge in power may have propelled women to be unfaithful but the male attitude isn't changing quite so fast. For a betrayed man, it's a slight against his manhood. It goes right to the core of his identity. For men, the sexual component of their wife's affair is very important – they are more concerned about the sexual aspect than if their wife loved the man she slept with.
'I don't think a woman's reason for having an affiar is that different from a man's – they're looking for attention and affection and that's going to include sex.
I guess the best advice before you make a mistake you might regret is better communication with your mate. Tell him how you are feeling and see if you can work it out. If you don't you might be headed for a blowup you are not prepared for.
