Fortune tellers always say that two people who break up will make up. Is it credible?

It feels like your relationship hasn't broken down yet. Your boyfriend may be really busy, or need a period of solitude to sort out contradictions and adjust his state. Because you broke up in name, he can directly refuse your request to meet without too much scruples. Staying with him may make him more evasive. If you want to make up, I suggest you show trust and respect to him, give him some free space, and slowly influence him with gentleness. Be patient.
