How do I say sorry to him properly?

there is the guy I used to bully for 2 years because he said he was half filipino half japanese but at one point I belived him until this argument happened over facebook that is when I had my doubts about him he has kinda wavy hair but he said he curls it here and there using a thing called 'perm' and that his hair is naturaly straight I thought he had gone mad but then a few days ago on the holidays I saw him at the shops with his parents and every thing he said was true he had straight hair and his dad is japanese and his mum is filipino I didden't know what to say when I saw he it was like I coulden't breath but he didden't see me I went to the food court where there was alot of people so he woulden't see me I felt bad and guilty because all that time he was telling the truth and now it's school now I see him at the bus stop and some times at lunch and recess but he never sees me im dying to appoligize to him but im scared can any one tell me how can I appoligize to him with out being afraid of rejection?

Part of making amends for past bad behavior is owning up to the harm you caused. Any rejection, anger, or negativity you may experience when you apologize is part of that. Remember, the apology isn't about you and your feelings. It's about acknowledging the harm you caused and expressing sincere remorse as a gesture to help the person you harmed heal from that harm.

Sincerely apologize and and tell him you truly regret hurting him. If he tells you to go to h#ll, let him and continue expressing your remorse.

If you haven't already, I hope you take a good look at yourself and resolve to never bully or belittle anyone else again.

just say "im REALLLY sorry for bullying u and everything I did to u in the yrs. I wish I could take it back."
