Why people cheat when they have awesome partners?

  How to prevent cheating has been the #1 issue plaguing all committed relationships since the beginning of time. Even worst when there are people who cheat on a partner who meets or surpass  one's desires in a relationship. Frankly, asking why do people cheat is kinda like asking why do people drink alcohol. That shot glass full of vodka didn't tell force you to pick it up and drink it.  There is no real logical answer as to why people do it; just really a matter of ones character or ethos as I like to call it.

First thing we must do is to define cheating:

Cheat: Act dishonestly or unfairly in order to gain an advantage, esp. in a game or examination: "she cheats at cards"  ....In other words: To be unfaithful (faith: means to trust or believe) 

So if you cheat, that makes you an person without character, untrustworthy. Now that we defined cheating I shall post a few possible reasons as to why people cheat on great mates.

1. They lacked morals the whole time: Let's face it, some people enter a relationship with the intentions of screwing you over anyway. Sadly cheater is synonymous with a liar and being faithful and chances are they have other questionable habits as well. One example, a supposedly straight partner who has a best friend of the opposite sex. If he/she was such a worthy mate, then why are they with you and not them?
   
   Advice: Mark you're property, the more time you spend with your partner publicly, the less likely the will try to cheat. Dump them the second they even utter such much as 2 words think they are better than you.
2. Humans are not monogamous: Well, if we were, we wouldn't cheat as often....simply because the rules of the relationship will allow for multiple mates. Polygyny (Multiple wives) - Has a few advantages economically ; women tend to be more attracted to men who are often seen to be attractive to other women (it is easier to get a girlfriend when you have a girlfriend). Chances are if a man can cheat on his partner he can support multiple mates....and if you are a polygamist that is more adults sharing their resources in a relationship this tripling the income, his sexual prawlious (he wont likely get bored), and not to mention the cost of the relationship will be virtually unchanged. Polyandry (Multiple Husbands) Chances many women practices this already; one example is women who have that 'guy friend' who basically does everything your boyfriend can't ....so in a way you are dating two men because chances are if your boyfriend was as skilled as him, you would not of formed that friendship. Another example, is a woman with multiple child support claims on multiple men, but no matter how you put it you are using multiple men to place substance in to one relationship. Many monogamous relationships have a nasty habit of calling these women sluts and whores...funny thing if sluts and whores where such bad people, then why do men find them so sexually attractive more so than a good looking woman who keeps her legs closed?
      No matter what moral emphasis you place on it, chances are if you ever been in love you sometimes will 'cheat' to hold strength to your own relationship. Monogamy is a two dimensional relationship and no man or woman likes someone who goes outside of the equation to provide what they should expect form them.
   
   Advice: Be a team player..... emphasis on the player. True players always keep a claim head and once the home wrecker realizes that they are just a Beta wolf, they will eventually abandon your mate. However if you loose your cool....you just promoted that Beta to your alpha position. (Use type one tactics as well)
3. Rebellious nature: Sometimes people will do something naughty just to be defiant. Sometimes there people in abusive relationships and they don't know how to get out of it. There are also people who wish to get something their partner is either unwilling or unable to provide. However, Instead of trying to negotiate their partner to bring a sense of mutual stratification.  This is like the Married man who goes to strip clubs, or the Married woman who enrolls full time in to college and takes the 19 year old boy the the movies. Chances are even if something sexual does happen the 'rebellious types' the to be the most loyal. Sadly, there only one type of rebellious mates on the market are the hoes. 
   
   Advice: Pimp dat hoe or Drop that hoe: A hoe can be male of female. It like this, just like how street hookers got put out on the street because of their nasty rebellious attitudes toward their parents, then they get exploited by a pimp. Well don't leave your relationship empty handed...if they gonna go sleeping around make sure they give you something in return ....other than a STD. No matter how you put it, You might not wanna marry that individual.
4. Lack of Appreciation:  Okay, this is a hard pill for all of us to shallow. Sometimes you are in a failed relationship and you are holding on to hopes and dreams more so than a combined livelihood. We can get so accustomed to having that security of living with someone who used to love us, but don't want to find security else where at the same time. Most men who cheat use this as their #1 one excuse; while most women would simply dump a man first ask questions later. Hell make it so bad, simple words like 'Thank you' and 'I love you' can sometimes make all the difference.
   
   Advice: Ladies: DO NOT CHANGE THE RULES OF YOUR RELATIONSHIP!!! True, the longer that you know am an the higher your explications and standards for the man you love becomes. However, men really don't like to change. Sometimes, this may require you to try or do somethings you wouldn't not ordinarily have done, but deep down in side all a man wants is a woman who is cool to chill with. Guys: YOU CANNOT FORCE A WOMAN TO LOVE YOU.  If you can't step up your game, then step away form her....if she loves you...turn around and see if you don't see her frowny-ass following behind you (stalking you basically) she may not be happy with your lack of game, but all women are attracted to realness...and Men who cheat lack that quality.
   
   
   

  At the end of the day asking "Why do you cheat?" period is like drinking alcohol, or masturbate, no matter how you put it cheating is a matter of one's character and character is defined by what someone does, when you aren't looking. If you are doing something that you are not willing to tell your partner then you are in fact cheating. The chances are if you cheat, you know you got an awesome partner at the end of the day.
