The fortune teller said that my boyfriend and I had very close birthdays, but why did we break up? The fortune teller said we were all fine.

Whether a fortune teller is allowed or not is just that you rely on what he says to you and your boyfriend. What he says is not allowed at all, so don't completely believe what he says, because what happens to most couples when they are in love is not a bad thing, but they often break up and quarrel. It is useless for two people to get along or maintain their feelings.
