boys, do NOT get married. Seriously.
Gents, do NOT get married. Seriously. There's nothing in it for you. Seriously.
Worst case - woman divorces you, takes the kids and half your shit.
Best case - you stay married and have to live with a shrew for the rest of your life sleeping with just one chick. No one is fun to be with after a few years. No one. The shit piles up higher and deeper.
EDIT> I've thought a lot about what you guys have said. Perhaps marriage is not the problem. Without marriage I would not have had our two beautiful boys who mean more to me than life itself. The problem is that I played myself. I was not true to what my own needs were, and was too accommodating. I should not have asked my wife to move in so early. I should not have settled. So perhaps a more balanced approach is to just wait until you're mid-30s before getting married. Learn from my mistakes.
