What are the reasons for family instability in modern society?

At the present time, a lot of married couples disagree, the reasons for this are not confidence in the future. Namely, not a stable salary, lack of housing conditions, in our time, not all married couples can afford to buy a house or apartment. Another disadvantage to my point of view is popular civil marriages, it seems to me that men living in a civil marriage do not consider themselves the head of the family, I would even say some generally consider themselves bachelors. And they simply relieve themselves of half of the male responsibilities, and can even afford treason. Cheating has become so popular in our time that some do not even hide it. To be honest, it is very disgusting to look at all this, people are so carried away by themselves and their interests that they do not even notice the children who live with them. Which require care and attention, love, because children need a family consisting of happy mom and dad. Family values, this is what modern couples have forgotten about, respect, understanding, teaching. After all, creating a new family does not mean living according to the old principles, it means that we have to re-learn, start everything from scratch. And only when we learn to hear each other, understand, and respect each other, we will be able to build strong relationships, and a strong family.
