Why do guys cheat?

Okay so my friend is constantally complaing about how her boyfriend is ALWAYS cheating on her.. & honestly, I don't understand why she doesn't just leave him.. but I'm just curious... WHY DO GUYS CHEAT?? maybe it's because at this age guys just want to...

have fun && explore their options.. but seriously why cheat?? does it make them feel like their not trapped ... or what?? I mean why not break up with the girl..?? Why continue cheating on her ?? I just don't get it !! ... && I'm hoping some GUYS will actually answer this question.! (=

because guys get tired of eating a big mac every day, sometimes they want to try a new type of burger

(= haha

HAHA that was a HORRBILE response.
probably true... but still.
why do the guys go back to the big mac then?
why not leave em & go for the fish fillet.
then the nuggets.

lol it may be true but I still can't understand WHY they just don't leave the girl they're cheating on though!?
I'm so lucky my man is faithful ! (=

haha not all guys cheat
just the retarded heartless ones that dont care about their gfs

I've never cheated, even if I have a crush on someone and we're not together I wont do anything with anyone else, is that weird or what? lol

but yeah, there are some good guys out there that dont cheat

and maybe it is this age, the raging hormones age...h*rny teenage boys...

Guys are not the only ones whos cheat, girls cheat too, and its not just teenagers either. Even older people cheat. I think they do for several reasons, two of which are that they are scared of being alone and also because the people that they are with allow them to keep cheating by staying with the cheater.

The only thing that you can do to help your friend is to tell her that if she values herself, she would not be with someone that treated her in such a disrespectful way. He will probably not break up with her and wont stop cheating on her, so she has to be the one to break it off with him.

People would probly cheat because some people are set out to do one thing, you can probly guess what that is, and if they don't get enough exitment, then they would turn to someone else, but some people are just pigs and cheat by keeping 2 girls. I find it kinda stupid, and sad that someone would ever do that. because people need to understand there are people who feel the same as you do, an acul person, no someone who is an object, of coarse since no body stops to take the time to think about it, they NEVER LEARN. In my book that is repulsive. I think ignorance is slowing down the process of evolution through our intellagence, and that all ignorance, and stupidity should be cleared away from the planet in total. But that is what I think, because I got to deal with it in a school full of red necks, oh well we don't choose the people in the world. But the reason people cheat is because they think it's exitment, even tho it never works out for them (sorry I got sidetracked witht the ignorance thing) in the end. Like starting a firework, it's exitment untill someone loses a finger. Hope this helps, if you odn't understand it, just think about what I mean.

Um? For the same reasons as girls do?

Actually, I don't think they are the same reasons as I recall reading somewhere.
Are guys not supposed to have this animal instinct to spread their seed around while girls cheat for more emotional reasons?

Sorry, cant remember all of the details...

because guys are pigs and need attention and us girls are stupid enough to fall for them
