"...That especially includes single parents who've elected to go it alone because they are unhappy with the choice they've made for a partner..."

My wife left her first husband after a broken jaw and looking down the barrel of his .44 mag, so I guess you could say that she was unhally with the choice she made in a partner. She then raised two kids as a single mom, working graveyard shift as a law enforcement dispatcher, taking college classes, doing her Navy Reserve time, being a room mom at school, taking the kids to their various clubs and interests, being an assistant Brownie leader, the list goes on and on and on. I have no idea how or when she slept. Beind divorced often has little to do with the quality of the parent. Not all divorced parents go on the Jerry Springer Show...
