People always want to know if it's ok to divorce? The correct answer is YES.
It's ok for any man to divorce their wife and marry a younger and prettier woman.
It maybe isnt such good idea to divorce his wife and marry younger and prettier woman. If the woman is only after the mans money then this will be a problem for him down the road in this relationship.
For a man with a family it makes it even worst for the situation. If the younger woman is close to age of kids it will make things even more messed up.
