Hey zzxxee,
Generally speaking men who cheat are insecure, always think the grass is greener and are forever searching for something that they wouldn't be able to keep even if they recognised it.
My ex husband cheated regularly and is very bitter that I left him. The penny does not seem to have dropped that I left because I cheated.
It most certainly does not apply to all men.
Girls/women/ladies who are attracted to this type of man are often insecure themselves and don't believe they are worth better treatment.
