I agree with you that divorce should only be used as a last resort, but what I am seeing is an epidemic of people in their early 20s divorced and with children. Many divorced before the child is one.
I have children of marriageable age so I subscribe to a shidduch listing were I get a listing of available singles. The listing only gives the initials, sex, the age, the shaddchun’s name, if divorced and if so how long, number of children, and a brief description. This is how I discovered this problem.
This problem is happening in all types of families whether they be working, rabbinic or Hasidic and there is a very good chance they will be living in a single parent family for years to come.
