I raised three kids with little help from their father, my family, the gov, etc. Three kids, same home, same rules, etc. Daughter is conservative (mostly), in school on her own dime, and has made intelligent choices. Two sons, neither in school, neither making choices I would prefer they make, but both working and living on their own. So far, no grandkids or marriages or addictions or abuse, or any other serious issues have arisen. Twins are 22, youngest is 20 - and he's struggling and giving me fits right now, but nothing a little "mom" in his face won't fix.
Yeah, it would have been a lot easier if I'd been able to stay married, finish my degree, had a normal family support systems, etc. But I really believe it comes down to the individual. Everyone has choices and how they react to the consequences of those choices is the deciding factor.
