THE MAN acts juvenile and immature
Not that the woman was perfect, nobody is, but I'd have to say 99% of the problems are caused by the man's juvenile and immature outlook on life.
And when he discovers that life is not just one big party, and he feels disappointed because he's just an ordinary joe with an average life..... he abuses his wife (not physically, but definitely mentally).
He acts like a little boy.
An immature juvenile.
Sadly I see this problem in a lot of married couples. Either the man or the woman are still immature in their attitude, with unrealistic expectations, and then they blame their partner (when they should be pointing the finger at themselves).
