I’d say for Cancer a Libra woman. It’s at least worked for my parents who have been married for 49 years come this February.
For a Libra a Capricorn woman. This is my aunt and uncles combo and they have been married for over 50 years.
My other Capricorn aunt has been married to my Leo uncle for over 50 years.
Then I have a Virgo uncle who has been married to my Cancer/Leo cusper aunt for 49-50 years.
Libra grandmother (dads mom) was married to my Aqua grandfather for over 40 years until he was killed in a tragic accident before I was born. She spent the next 30 years dating different men well into her nineties. Every time I’d go and visit her she’d have a new man in her life. 😂. At one point she even dated my Scorpio grandfather (moms dad) for awhile which was a bit strange…..not gonna lie. My hope is to be just like her and to still be getting it on when I’m in my nineties! 😂
Idk maybe things were just different back then and relationships don’t last as long these days. 🤷♀️
