Why it's hard to find Good relationships in our era ???

I think it's been true for all eras, we just white wash history and talk about how much better those times where, but when you look into the details there was a lot of cheating then...

And a lot less cared about cheating... there is stories about people cheating on their spouse and nothing they could do.

Only difference is we break up more often because that's more socially acceptable now.
