If I cheat on her, she gets half my stuff. I she cheats on me, she STILL gets half my stuff.
Finacially it doesn't make sense to get married especially with the risk of divorce. As far as the spirital realm goes, I have to get married-fornication is against God's law as well as celebacy-we are commanded to multiply and replenish the earth.
One word: prenups.
Getting a pre-nup is NOT a sign of a lack of trust. A friend's mother literally went insane from a mental illness, but before she got so insane that she could be forced into a mental institution, her husband divorced and she ruined his finances. Always get a prenup, if no other reason than for the possibility of literal mental insanity. These were conservative committed Christians BTW.
