Families can be so different. Some people should never have had children......but it happens all the time. Sometimes I think for us baby boomers, our to-be fathers came home from the war and were afraid that life was getting away from them, so they "settled" for the first woman who came along. Also......I think many people thought you had to be married to have sex, so they married for that........and when the interest in that wasn't so great, they realized there wasn't much else.
We were a very troubled family..........as were some of the other neighbors. But then there were the ones we envied, who seemed to have parents who actually loved them.......and were healthy emotionally themselves.
Everyone is different in how they can handle things. Of course, my bias with toxic parents is to lose them ASAP. But maybe those who have had better families growing up.....they can say to be kinder and more tolerant. It's not an easy thing to deal with.
