Job provides a salutory lesson in the things that we fear coming upon us and, of course, history often repeats itself through generations.
Why did you hate coming from a 'divorced family'? Whatever the reasons, presumably you've learned enough from your experience to ensure that your dc have a more positive view of their dps living separately than you did.
Were so you so foolish as to let fear of the 'd' word influence your decisions, I would imagine that some, at least, of your dc would come to hate being the sticking plaster that keeps their dps stuck in a stultifying marriage and, quite possibly, come to despise either/both of their dps for being such abysmal role models for intimate relationships.
As for not picking another dickhead, there's no guarantees in either life or love but you can minimise the risk by discarding any who have form for illicit legovers and/or telling porkies whether to themselves or to others, and eliminate those who need to be dragged kicking and screaming to the plate of responsible adulthood and parenthood.
However, before you set about casting your net for another catch, you're best advised to spend a considerable period of time reflecting on why you want to land what could be another dud when it's perfectly possible to have an intensely rewarding and fulfilling life without having a live-in paramour cramping your style.
