Ah, the age old question... Why do guys cheat? Many reasons.
In no particular order..
1. Because they don't know what they already have.
Let's over generalise here for the sake of simplicity. Some guys just have very low self esteem, hence why they will not realise what they have until it's gone. Or, as the case is more likely to be, they don't know what they have until they see other people wanting it. They see a new girl that the other guys are keen on and to prove their own self worth, they pursue it. They don't have enough confidence in their own decisions, neither in their own convictions, so they conform to what is in mass demand. Without third-party confirmation, they just don't know what is good and what isn't.
2. Because they think they're special.
Men with powerful influential jobs sometimes confuse this power and influence in their personal lives. They have A-type personalities; ultra competitive and ambitious. They want to be the best and always looking for a challenge, they don't want to stay in one spot too long.
See how easily that could be transferred in to one's personal life?
Think about the celebrities who cheat on their wives. You would think that being married would mean the end of such things. But unfortunately no. It's not even like they're cheating on Anne Widdecomb lookalikes, they're cheating on the likes of Liz Hurley, Hilary Clinton and Elin Nordegren, so what hope does that leave the rest of us? NO! Don't think like that! The fact that men can cheat on beautiful, intelligent and self-made women goes to show that it's really not so much about us, it's about them.
3. Because they got married too early.
This can almost go under the first reason; they don't know what they already have. But in this case, they did know what they had, they married it, and then later realised that maybe they should've played the field a bit more for some genuine appreciation of what they really have. Or quite simply, they thought they had it good but then realised it could be better later on. No one's at fault, people grow apart. Romantic as it is to marry your childhood sweetheart, if you're 35, married for 15 years to a person who you no longer have anything in common with and is not even on your wavelength, it would be understandable to break up. Cheating however, is just the cowards way out.
4. Because he's not ready to commit.
You're perfect, he's perfect, it's the perfect relationship. But then you find out he cheated on you. And with some girl he doesn't even care about. And she's ugly. The only question you have is "Why?"
This whole thing can be summed up with one sentence I heard recently.
"I want to spend the rest of my life with her, I want to marry her, but just not yet."
In other words, this is the girl I want to spend the rest of my life with, but I'm not quite ready for the rest of my life to begin. (When Harry Met Sally anyone?)
But not just that, it's the stability and the perfectness of the relationship that scares him. He still wants to play, but he knows that the relationship is too perfect and there's only one direction it's heading in.
It's that needless self destructive behaviour that has us reading articles like this one.
5. Because they thought they could get away with it.
Pretty self explanatory this one isn't it? Also over laps a little with the second reason a guy thinks he's so special that no one will ever find out and the only people who do know are inconsequential. Sadly, if this is the reason he did it, then it's grounds for breaking up anyway since it shouldn't be about whether or not he would get caught, it's about how much he respects you. Sure he probably thought something along the lines of "What happens in Vegas stays in Vegas". But does it really? Try telling that to your doctor the next time you're at the GUM clinic.
6. Because they're scared.
Scare to be alone, scared of making a mistake, scared of breaking up, scared of hurting you blah blah blah. You've heard the excuse and the obvious response is "So you cheated on me?"
It's preposterous isn't it?
The reality is that they just wanted to have their cake and eat it. Maybe he still loves one girl but meets another who he also really wants to get to know because they just "click".
Blah blah blah...
In fact, this whole article should just have one reason:
Because (some) men don't have the backbone to break up before he gets with someone else.
