How does a man's fear of commitment relate to him being a cheater?

cheaters always have the same sob stories, that they were cheated on and it made them afraid of commitment forever. well, it sure as hell didn't make him afraid of dating or having sex. the fact is, some people are liars and cheaters. partially because they are charming enough to get many different partners and partially because they have no conscience. the only link i can see between fear of commitment and cheating is that fear of commitment is an excuse for them to cheat. i've been cheated on multiple times and still never cheat on anyone. i'd always want a committed relationship. i know guys who've been cheated on but they still are the committing type. and guys who were cheated on but they were also cheating at the same time, later they keep making this excuse forever. they cheat until they get caught and then they say oh sorry, i'm actually afraid of commitment, i was cheated on. bull crap, someone who's heart is truly broken even once would never ever break anyones heart. and if they do, they definitely deserved worst than what happened to them. you r lucky you found out about him before getting engaged or married. you should kick him to the curb and find a committing kind guy. the simple fact is there are two types of men, committing and non committing. loyal and cheaters. brave and cowards. just like there are good and evil people. besides even if we decide, he has some psychological issues, you cannot mend him. he is not a broken toy. i donno why we women wear the mending hat and keep trying to fix good for nothing men. even psychologists mostly fail to heal such people, we are not even qualified. just find a good piece that you don't have to fix.
