Starring: Lucille Ball, Desi Arnaz, Vivian Vance, William Frawley
Lucy Misses the Mertzes - S6-E16
Other mistake: When Ricky and Lucy go down to the main floor of their new home to 'inspect' for burglars after hearing a noise, the outside wind is loud and howling, yet the trees outside the bay window do not move, indicating this was shot in a studio.
Lucy Ricardo: Ricky, I'd like you to meet my second first husband.
Trivia: Fred and Ethel's bickering relationship didn't require much acting; in real life Vivian Vance and William Frawley didn't care for each other at all.
Answer: There is no reason. It's a just a silly plot device, typical of the era. Women characters were often portrayed as making uninformed assumptions or decisions.
