The fortune teller said that my boyfriend and I would not make up this time. Can you believe it?

If I were you, I wouldn't believe it. But you might believe it. Because fortune-telling always implies to your brain that "you and your boyfriend will not make up", which will make you miss the chance to make up. So whether you two can make up depends on whether your boyfriend comes back or not. If your boyfriend is kind to you, you should say yes. You tell fortune just to make up for it! I suggest you forget to tell your fortune. If you still like your boyfriend, show it on your own initiative!
