Speaking from personal experience, finding the right relationship can be HARD. I recently came across a rational take on finding relationship partners, much of which really resonated with my experiences:

(I'm still working my way through the Sequences, and lw has more than eight thousand articles with "relationship" in them. I'm not promising the linked articles include unique information)
I do not believe that marrying good people is sufficient to make divorce laws irrelevant, unless you define "good" so strongly that it's basically impossible to be justifiably confident that one is marrying a good person.
I'm talking on a personal level, not social. In the same way I would suggest that you not rob anyone and if you follow that suggestion, laws about robbery will be irrelevant to you (insert the usual disclaimers).
