"force their men out of their homea and into affairs"
The is the lamest excuse ever. I do know a lot of men and women that do cheat on their spouses because the sex life at home has been dead for years, and it is hard to decide what to do when the magic in a marriage dies, but blaming your spouse is not only wrong, its unfair.
It take 2 tango, If there is no sex at home, then both sides of the couple are at fault, and they should work together to solve the problem. Some couples will allow extra marital activity to solve the problem (and sometimes in unique cases that solution actually works), but if you have to lie and make excuses to justify betraying-cheating, then it would probably be a better idea to look into divorce.
Never ever accept a lying, excuse making, cheating husband (or wife), and never ever blame yourself for his (or her) betraying-cheating.
