Jim Thome's wife says the couple is done with the Browns following the Deshaun Watson signing ... explaining she's asked the franchise to cancel their season tickets.
Andrea Thome made the announcement on her Twitter page following Watson's introduction ceremony last week ... saying the sexual misconduct allegations against the new Cleveland quarterback were too much for her and her former MLB star hubby to ignore.
"Very sad after 40 years as a fan, but this is my line in the sand," Andrea said.
