The happiest & "richest" couple I know never got married. They had and raised great kids together, basically did and enjoyed the same things married couples did, and are now happily retired. Key to their relationship is that there was never a piece of paper binding them. The door was always open -- either could walk away at any time (barring, of course, support & legal obligations). They stayed in their relationship because they both wanted to stay in it for their love of each other. That is a commitment no marriage certificate can make happen.
I definitely agree! It seems that when the door is always open for one or the other to leave, they stay together because they genuinely love each other, they work on the relationship and thus it is those relationships that truly last. That is something that's the kind of relationship that I hope to have the next time. You really don't need the piece of paper to make it work. I think what some people want is the grandiose ceremony in front of friends as if to prove their love for the other. No thank you. I don't need it, but I'll never say never.
