What should my girlfriend do if she keeps in touch with her ex-boyfriend?

Let go, even if you persist like this now, there will be no result. She doesn't love you, she should just look at you and be with you. Or you can tell him frankly what is the relationship between you two, and come to a confession office to see if you can fix it. Also, the fortune teller said don't believe it. If there is no scientific basis, why believe it?
