I think you beat us to the personal by telling me I should go ahead and not get married. It’s too late for me. I’ve been married for half a century and will be married to my wife until the day I die. However, if some monetary circumstance - such as health care premiums - were to become financially crippling because we are legally married, it would be worth the hassle for us to obtain a (meaningless to us) civil divorce. The government’s view of our marriage does not change its sacramental nature.
Don't make things up, I didn't suggest people not marry, I only informed that they have always been able to call themselves married without complying with the law, if you want to do that then do it.
You describe two men living together, well they could do that in 1776 and 1976 and the year 1000 and call themselves married if they wanted to, they couldn't comply with law though, it wouldn't be legal.
