The reason a man would lie and mistreat a woman that is good to him

According to http://help.com/post/234488-can-anyone-tell-me-the-reason-a-man is because:

• He may not value any relationship. He can not commit so each relationship is just a means to an end. He is just in it for what he can get out. He expects every one to do their part except for himself. He has a false sense of manhood and probably drew some beliefs growing up that that is how woman should be treated.
• Many reasons, maybe he doesn’t like the girl, maybe he doesn’t like himself, maybe he doesn’t like life, he has a complete lack of respect for women.

• Some simple reasons
  -He doesnt like her
  -Doesnt feel worthy
  -Scared of commitment to such a thing

  For some reason, there are many people, most are males, that have a tendancy to stray. Apparently it comes from a sense of boredom, often resulting from lack of emotional attachment.

  Some males think about themselves more than their significant others.

  There are also different types of cheating. Some do it once, then confess for guilt and never do it again. Others though do it prolifically for no apparent reason.

• It is very strange why a man would do something like that, depends on what exactly..
  But in fact sometimes the man does many things to test the love and patience of a woman. Trapped in love yet wanting to be free they lose their minds so many times.
  To lie especially of unfaithfullness is easier then to tell the truth, face being judged, unforgiven and losing the one precious thing in ones life…In another form of mistreating a woman that is good to him and possibly loves him…Most probably because of dominance, afraid to lose control, afraid of losing the person, it mostly hides between what they have learned how to treat a woman etc from not so good people…maybe from abuse father or tough love scenario..anger frustration, tension misunderstood that can lead to emotional outbursts..the man probably behind it all loves the woman, is scared of losing and at the same time testing the woman’s love…all around is a circle that doesn’t seem to stop…at the core of tension and fear if that is found out and dealt with it should solve the situation..
