But Dennis says that he’s not a bad guy; he’s just been hurt in the past, and it has stayed with him.

“It really hurts when you get cheated on, doesn’t it?” Dr. Phil asks him in the video above.

“Yes,” he replies. “It kills, and it’s happened since the first girl I was with and every girl I’ve had after that. So, I developed a bitter taste in my eyes and my mind for women, because I’ve seen them all as sluts because every one I was with was with that, and I’m sorry for that because not every woman is.”
