some people cannot commit to being with one person even if they have it all, some people need to seek out excitement by cheating or enjoying the cloak and dagger of it.
Some people just cannot cope with the idea of only being with one person, and of course some people just get bored, if the relationship is rocky it just speeds up the process of cheating.
I dont believe that -as we are all human and not infallible.
One drunken misdemeanour shouldnt mean that your life as a couple is over.
U have to remember they live different lives -which means they are often more apart then together and thats like me and H -its tough to maintain that kind of relationship -very tough -let me tell ya grrrrrrrrr
