3. He wants to apologize for something mean he said.
He might be feeling regretful about something he said when you broke up, and is looking for the opportunity to apologize. It is possible for this kind of message to come at any time after a relationship ends. Sometimes immediately, sometimes six months, and sometimes even a year after you two have called it quits. Be gracious about accepting his apology but don’t interpret it as a desire to rekindle the flame.
