I’ve heard the terminology a time of two. According to yourdictionary.com the definition of a trophy wife is “a wife, often, specif., a second wife, who is attractive and younger than her usually wealthy husband and regarded as symbolizing his success.”
I've been called a trophy wife and I'm a lot more than that, I am the powerhouse which keeps him running! In return he keeps me running, I work full time while keeping our bills organized & all paid on time, cleaning, doing the laundry, making dinner (almost every night), taking care of our dogs (Joe helps too), planning vacations, arranging get togethers with our friends, hosting parties, hosting family holidays... the list could go on.
My husband may not be a rich man by means on money, but he is rich in the love he give to me & his family. I love my life and I love being his Trophy.
