I see almost no advantage to getting married other than it gives you and your spouse the satisfaction of saying 'this is my husband/wife'. Other than that there are not any significant benefits to the proposition and so many ways it can go wrong. I know too many people who are: unhappily married, divorced, paying alimony, paying child support, been cheated on, cheat, been married 2/3/4 times (do you learn??) and the list goes on. Honestly, what sense does it make financially or otherwise?
