Live with a woman, have lots of kids, but never, ever, ever marry. It is better for the kids as well. At least they will always have a loving dad who is not destroyed by the disgusting lawyers and courts, as I have seen so many great and decent guys.
Previous generations expected to be with the same mate forever. Recent generations watched their moms and dads divorce, shack-up, remarry (or not), divorce again, end up lonely, etc. It's no wonder today's women want to do it "different" than their mom's.
This is not the fault of divorce courts. It's the fault of the parents who selfishly ended their marriages and raised a generation of terrified adolescents. I'd like to see the statistics compared between young adults who willingly find mates and marry versus young adults who can't commit or claim they can't find mates. I'd bet a high percentage of unmarried women and men come from unhappy families.
