"Love and marriage have very little to do with each other."
Well, obviously if you go into a marriage with that mindset then you are doomed to failure. Duh.
The divorce rate has been in the neighborhood of 50% for about as long as divorces have been (relatively) easy to get. I know people that have been happily married for decades and others that have been divorced multiple times. Some people want it and some people don't. Some people are cut out for it and some people aren't. Some people make good judgements and some people don't. Some get lucky and some don't.
It seems like just yesterday the LGBTQ community was fighting for equal marriage rights. Now the thing is nobody should ever get married. Make up your mind society.
