Unfortunately most of us aren't taught how to choose a potential spouse and how to create good relationships and strong marraiges. (I've heard that in the mormon religion this is formally taught, but for the rest of us we're winging it).
It's kind of a shame because happiness is rooted to our connectedness with family and friends. If you think about it, a stable and loving marriage is going to help make for a better life. So.... pick up one book for now... but then after you finish it keep reading!
There is no arriving, ever. It is all a continual becoming.
