"To err is human and to accept is divine", mistakes can be committed by anyone but what is important is to accept them and apologize.
Asking for an apology is the first step towards a successful reunion.
When you meet, admit your mistakes and assure that the same would not be repeated in the future.
The next important thing is accepting break up and moving away with it in dignity.
Do not plead or become aggressive on your ex.
When you walk away gracefully, maturity is displayed and your ex will respect you for this.
