A person who knows the man or woman is married but still goes for it. This low life of a person does not even care that there is children involved. This scumbag may even look for problems in the marriage and try to make themselves look better by using that time of weakness. In some cases they may not be successful in breaking up the marriage, but are successful in breaking your heart and making you question everything in the future.
She started with Facebook , her and my husband talk. She told me she was happily married and she was not one of them crazy x-girlfriends. I told them that I didn't want them to talk anymore things didn't add up. She was using our problems and acting as if she worshiped the ground he walked on. And only he can understand her. (Boosting his ego) Now she's unhappy in her relationship. I told her off, and she spoke to me as if she was the wife and mother of his children! Needless to say it went back and forth. He clams she is out of her mind to think that she had some kind of future with him and our children. He clams he never wants to talk to her again __ Like I said "they are successful in breaking your heart and making you question everything in the future"_ Homewrecker
