In Wednesday night's episode of the soap (December 4 2019) she outed Robert to their family and friends at their wedding, after having recently managed to get him to sign the Bistro over to her.
After the wedding drama, she later told her family she was selling the Bistro and would be moving.
She knocks everything off, throws things and smashes the place up.
Next week, a woman calls at the Bistro representing an anonymous buyer and learns the offer is near half of the asking price.
Carla advises her to consider it for a quick sale and it's not long before Michelle is instructing Adam to accept the mystery buyers offer.
It is later revealed that the mystery buyer is Michelle's sleazy former boss - Ray.
Actress Kym Marsh, who plays Michelle, told ED!: "She's furious about that.
"Of all the people to buy the Bistro it's him, the slimeball! He's the last person that she was expecting.
"She doesn't take the news well and contemplates trying to change things but it's too late.
"[Instead she thinks] I'm just going to smash the place up! She knocks everything off, throws things and smashes the place up.
"For her it's everything mounting up. The events of Christmas day, and everything afterwards. She's in a bad place at this point."
Coronation Street airs on Mondays, Wednesdays and Fridays at 7.30pm and 8.30pm on ITV.
