Marriage Is Not a '24/7 Sleepover Party'

I wonder if they control for couples who have kids versus those who don't.
However the advantages to a marriage are financial (2 providers vs 1), emotional (if I'm down or vice versa, she's got my back), sexual (no more bar hopping looking for sex), disease preventative (if we're both faithful, I don't have to worry about STDs at all, except for possibilities in hospitals), skills (she has one set of skills, I another, combined we compensate for weaknesses of the other. It hurts when we're both bad at something).
Many advantages, MARRIAGE though... idk... it made no difference to us when we got married. We knew that splitting up or divorce was equal in our eyes, the relationship was too important. Marriage gives us also legal benefits, that's all we really cared about.
