I don’t think TRP can be transferred, it’s learned and manifested. How can I get him to understand this without wasting my time?

It’s the typical, clinging to the girl type of shit even though she doesn’t reciprocate. And it’s been going on, for months, after breaking up. They weren’t even dating by the way, just casual sex. He’s got better than average looks. If you guys want to know more about this person and/or his relationship to better understand the level of blue pill, please help me help him.
