She never expected that her high school sweetheart would be coming out as transgender.
She said, "I would have never thought that in a million years from knowing him from high school. When it came out in the papers that he was thinking of this, I think everyone was really shocked."
Michelle wishes Bruce the best in his journey.
"I hope he figures out what it is that he would like for his life. I hope that he finds happiness and that he is in that," she said.
