I think she was smart. She saw what happened to Nicole and didn't want the same to happen to her.

I think she blindsided him and good for her. I think if he would have known, he would have made the announcement and controlled the entire thing. He would have made it look like he left her and wouldnt have been holding her hands and gushing about her in interviews. He is probably super embarrassed and feels like a fool. You can only kick a puppy so many times before it bites back, and i think Tom was just bitten!

I THINK THATS ITS DN KNOW MATTER HW IT WAS PLANNED TIME TO MOVE ON
