In what way? Adultery has always been a cause for divorce. I do believe the ease of no fault divorce has weakened marriage.
There is no such thing as no fault when a man divorces a woman, he still gets screwed in the end regardless of the reason.
A college friend divorced his cheating wife after 6 years and 1 child. He sadly lived in a alimony state and had to pay not only child support (which he should) but he had to pay more in alimony to her skank butt. The court would not give him primary custody even though he had a good and stable 8-5 job. She was using both the alimony and child support to paint the town. Divorce laws are BS.
pre no fault there were more than a few cases of “made up” reasons.
he accuses her of cheating or vice versa. She accuses him of “not being interested in women” and so on. the truth may have been simply they were a wrong match and should never have married.
even with the lies, I am unaware of any case of a divorce being denied ever. Divorce happens so why clog up the court records with needless dirty laundry real or made up.
