GirlFriend im just asking... Why are people so selfish when it comes to relationships?

Mood : Just wondering

Girlfriend I'm just asking ...is it me? or does everyone JUST think of THEMSELVES.

So I was talking to a friend of mine.... he is young and accomplished... he is married to a young lady who also has a career and they have a child together.
But my friend cheats on his girl and says that " he doubts he will be with her for the long run".
So I asked him.. why do you stay? and he said for my Kid.....
In my eyes i think that's a scapegoat.... raising your child in a dysfunctional home JUST to say they were raised by two parents.
So I said the both of y'all are young and you ONLY live once -- why not get a divorce, go your separate ways and find love with who you truly should be with.
HE NEVER EVEN CONSIDERED IT......
In his mind... he was going to keep the Fairytale wife and kid so that it looks GOOD in everyone else eyes and behind closed doors he is unhappy and seeking happiness else where.

So my question is in this Situation why is he being soooooo selfish?
Why wont he let her go instead of subjecting her to being mistreated by him?

So my question is WHY DO PEOPLE WANT TO HAVE THEIR CAKE AND EAT IT TOO? and WHAT MAKES PEOPLE CHEAT.... wouldn't it just be better to Leave...

Let me know how you feel.
