Sent him a short message.

You encounter such a situation, that is, your boyfriend broke up with you for three months, and he suddenly sent a message asking you not to bother him in the future, and said that he would say goodbye to you forever. I think I should be angry. Otherwise, why do you say that? Besides, you had contact with him, which should be the case. This shows that there are no contradictions and mistakes in principle between you. If after a period of calm, two people can talk calmly together, I think things may get better. And I really hope you two can make up. After all, acquaintance is fate, so we should cherish it. This is the right choice. Now, I wish you happiness.
