Some women of all ages that have a cheating mate sometimes feel it is their fault; they are not pretty enough; they did something wrong, but don't know what they did wrong. Some men of all ages will cheat no matter how attractive and intelligent their mate is and it is not her fault. You cannot prevent a person from cheating on you, but you can get control of your own life and be more independent and kick his hide out the door and start getting out with friends; having fun and start dating other men. There is someone special out there that deserves you and you should not tie up your life with a cheating man.
