Ok, so my ex-girlfriend is hung up on my old roommate. How do I destroy any connection to him? I told her not to hang out with him, but I feel like she just does it more because I told her not to. Of course, at the same time, he is a very like-able guy. He used some pickup trick on her I believe. I want to reverse whatever he did, win her back over, and sever any connection she has to him. This relationship between them has been a source of heartache and emotional turmoil. Please only experts/serious answers.
