When some men are married for a year or so and realize that it is much different than just dating and both couples need to face reality such as both working towards the future or, after several years of marriage the married man feels restless as if he wants to reach back into his youth and needs to know other women are attracted to him he will find a mistress. The wife has had to put up with him for a year or several years and sometimes boredom can set in for the husband, but meeting someone new is exciting and the sexual relationship is as well, but if the married man keeps seeing the mistress for a fair length of time he will soon realize that 'the grass is not always greener on the other side of the fence) and he is once again bored. Some married men will find another mistress or, they may return home to their wives and settle down. Basically, these types of married men become slightly obsessed with their mistress because their relationship is new and exciting and he has no commitments. This is a high sign of immaturity on the married man's part.
