Concentrate on girls who come from MARRIAGE FAMBLIES [i.e. their Mom & their Dad are still married, and there's no history of Aunts & Uncles nor Grandparents divorcing].

Whereas if you're dating bishes from Divorce Famblies [parents divorced, grandparents divorced, aunts & uncles divorced, etc], then you're just asking for heartache & despair.

AFAICT, the distinction between Marriage Famblies versus Divorce Famblies is inherited, i.e. is in the genes, and if you hook up with a bish who has the genes for a Divorce Fambly, then you're life is gonna be Hell on Earth.
