However, Michelle is only 14 – and her parents completely disapprove of their relationship.

So why is he continuing to date a minor?

“When I’d first met her, she falsely informed me her age,” Paul tells Dr. Phil on Thursday’s episode. “After we had done things together and been talking for awhile, and she’d been staying with me, I had already figured we’d taken everything as far as it could be taken. Then, I find out her real age. So, I figure I’m falling in love with the girl, why break up with her?”

Dr. Phil points out that because Michelle is a minor, Paul could end up in trouble with the law.

“You do realize that it is a violation of the law?” Dr. Phil asks the teen. “And you said you also went out and got drunk, which means you were also plying her with alcohol, which is contributing to the delinquency of a minor, which is also a crime.”
