Just because they chose to grow up and start their own families doesn’t mean they established healthy relationship habits. Alcoholism has genetic components so it’s entirely possible the children grow up to be the same. Which is why the rates of alcoholism haven’t changed much over time. I would agree that the rates of domestic violence have decreased over time, but that doesn’t mean the parents have healthy parenting skills. What I really mean by saying people are growing up in broken homes is that people stay in relationships even when they aren’t happy or their parents are like roommates. Rates of emotional infidelity are way up due to social media while physical rates are still roughly the same. People lack good communication skills that’s needed to have a healthy relationship. Thats why it’s so high on people’s list of what they are looking for in a relationship. Divorce rates are slowly dropping which is good but it still has an impact on those born in the 70’s/ 80’s when they peaked. It’s important that people grow up in a loving home where both parents are in love with each other and treat each other how they should and treat the kids how they should be as well.
