The key difference between preventing a third party and cutting ties with one
One is a platonic friend, the other is your lover.
This will also affect our boyfriend's love for us. After all, once he becomes the other woman's lover, he won't just be sharing his affection—he'll be preparing to break up with us.
However, based on our experience, those who typically seek our help are already dealing with a third party. When relationships are still sweet and new, we tell you to start guarding against third parties, but no one pays us any mind. So it's the same mindset, same problem.
