When someone call you a matriarch?

Answer 1

It means the woman has the power in the relationship, so if you're female....then they're calling you powerful.

Clarification:

A matriarch is the female head of the extended family, which is usually the eldest female member. It can be your grandmother, mother, aunt, etc.

Likewise, a patriarch is the male head of the extended family, also usually the eldest male family member.
