Relationships don't work anymore, it's not like the olden days. Men cheat because the women don't pay attention to there man. Nobody knows how to treat anybody anymore. I can get in detail but this msg would be 1000 words. Everyone is to busy but they end up getting a dog or 2. How do they have time for a let, they don't So what's happening is people are treating people like dogs. They just pay attention to them when they feel like it. That doesn't work in a relationship.
I agree with your first sentence.
Everything else though is in my opinion and based from my 50+ years of a multitude of relationships, is a narrow view.
I am of the mind that relationships never worked. Humans are not meant to be monogamous in perpetuity. Serial monogamy yes, forever, no.
As far as people treating each other poorly, I don't think that is true. Basic human nature is to be kind and to look after one another. If something derails and the ugly's set in, well that is unfortunate but the default is not to be unkind to each other. If that is the case something created that situation.
Kudos to any couple out there who have a real lasting relationship, and not the ones who just stick together just because. Real loving, active, involved relationships, you are the exception.
OK, soap box is now vacated.
