I’ve witnessed a lot of that abusive behavior. My late parents were married for 50 years and pretty much couldn’t stand each other for 45 of them. Divorce was more stigmatized in those days, but it would have been the wiser option. The eye-rolling, sarcasm, accusations, innuendos, and downright nastiness was always difficult to behold. I have two brothers and all three of us have been happily married for many decades. My youngest brother says that he just recalls what our parents did and does the opposite. Works well.
xsteen has seen this behavior in a few friends relationships and is horrified by it. they will likely marry, and it does not bode well for them if they are doing it from now.
Oh that is so sad - my parents were madly in love and it showed. I never once heard them argue about anything
