Hi Jacoby,
Yes, women who have parents who are still together are typically great candidates for long-term relationships. Women like this will often want to emulate their parents.
An effective way to filter out a woman who won’t make a good wife or mother is to observe the people that she keeps as friends and acquaintances.
If she typically associates herself with people who tend to have bad relationships with their romantic partners and children, there is a good chance that she will do the same if she were to become a wife or mother.
