As far a marriage having agreement on the big three: Money, sex, kids is helpful. This has long been known.
For me beyond that my only wish is that my partner be herself, cares about me more then my money or what I can do for her, that we like each other and similarly can stand each other, and our lives are heading in a compatible direction.
I have a wonderful wife and we have been together over 20 years and it gets better every year.
