If I am really wrong, how can I save him?

1. Tell him I was wrong and sincerely apologize to him.

I want to express my deepest apologies to you through this letter. I realize that I made a heinous mistake and hurt your feelings, and I regret it very much. Anyway, I can't let this mistake continue to affect our relationship. Please believe me, I sincerely apologize to you, and I hope you can accept my apology.

2. Admit mistakes and seek opportunities for forgiveness and change.

In the process of getting along with us, I understand the harm that my mistakes have caused to our relationship. I deeply realized that I didn't realize the conflict and harm between my words and deeds. However, I want to tell you that this experience is a great inspiration to me. I sincerely assure you that I will take all necessary measures to correct my mistakes and ensure that such mistakes will not happen again. I ask you to give me a chance to forgive me and let us rebuild the trust and happiness we once had.

3. Try to rebuild the relationship and show sincere care and love.

I know that just a few apologies can't completely repair the rift between us. Therefore, I will work harder to regain your trust and let us go back to the happy days in the past. I will show more care, consideration and understanding, as well as the support and care you need. No matter what happens, you have always been an important person in my life, and I am willing to work hard for our future. Please give me a chance to make up for my mistakes and redefine our relationship. I sincerely hope that we can start over and create a better future together.
