Here's a hint before you decide to get married:
Hang out with the families first to see what traits you will be dealing with.
My father in law is a self centered sloppy pig of an ex- Marine.
So guess how my wife acts? It's all her. It took ten years to convince her to stop saying, "I gotta hit the head."
She's just like her dad in housekeeping - I'm constantly picking up after her, dishes are scattered everywhere, etc.
My mother in law is in a loveless marriage, and screws every guy she can. Consequently, my brother in law is a sex maniac that doesn't know how to have a relationship.
That's about it - the names "Momma's Boys" and "Daddy's girls" are true- look before you leap!
