The fact is that in the past women were supposed to stick to their husbands, regardless if they were moronic d*cks. Who only cared about themselves. Luckily now days, women are able to care for themselves, and we as a society accept that. Which gives women more leverage to leave men, and thus why we see more divorces.
Thus why you want to get to know the other person really well, and if possible live with them before marriage.
there is no shame in being single. It is better than being miserable.
Very wise observations! However, don't assume living together is all it's cracked up to be. I know of several friends who did this, and STILL ended up divorced. What is it about that little ring of gold that changes things? Hmmm....
