That' a whole life to spend, you spend it happy or you spend it sad.
There is a popoular saying here in our community that says: (translated word by word):
"Invert the jar on it's neck, a girl becomes as her mother" that means usually a girl inherits from her mother carecteres. and generally a girl will behave as her mother did.
Most of times it's true and rarely it's wrong!
So before you marry a girl,(I'm speaking for men) look first to her mother's life with her husband ( your fuiture father in law) whenever he's happy in his conjugal life, so you will be with his daughter. If not! think a lot before taking an ultim decision. Good luck
