Coming from a divorced family, I understand and want this yes. But I am not niave about statistics. With no fault divorce existing and the existence of shitty laws you never know how society can influence a person, even we'll meaning. For example, who's to say I don't end up in jail for a lifetime like Ross ulbrict for a victimless crime? I don't think she would divorce me for that, but I myself would say after I'd been in jail for certain number of years and exhausted appeals that I would tell her to divorce me. Same if I was paralyzed. I will never myself ask for a divorce but shit is complicated dude and no one goes into a marriage wanting a divorce yet 50% of marriages fail.  

 Then have kids , live together and just don't get married. Seems like you are missing the point of marriage.  

 What's the point of marriage and if it is something other than a legally binding contract with the government, why is the core distinction between being married and unmarried the existence of a contract with the government?
