The number one thing I don't want to emulate from my parents is getting a divorce. My hubby's parents are also divorced so yeah, definitely don't want to be like them.
Generally have not thought in such terms except for wanting to live a happier life than they had. They were not perfect and both drug-dependent but as I age I'm more willing to see them as having perhaps done the best they could under the circumstances. Which I was unwilling to acknowledge living with them or to some extent even while they were living.
