If your boyfriend cheated on you to save her boyfriend.

Dear, I know that you have been suffering and disappointed recently because of what I have done. I came to apologize to you. I was really wrong. There was a moment of confusion, not to cherish the feelings between us, but to look for excitement at will. But now I understand how important you are to me. You are my only lover and the most precious person in my life. I admit that I made a mistake, but please believe me, I will use my life to make up for my mistake. I love you, you are the one I love. Please forgive me and let's start over.

I know you may have doubts about me now, but I hope you can listen to me. Our relationship may have suffered setbacks, but I believe we have enough love and trust to repair it. I will use my words and deeds to prove my sincerity and determination, and use my future actions to pave the way to happiness for our relationship. I hope you can reconsider our relationship and give us a chance to start over.

I can understand your disappointment and distrust of me. However, I think from the bottom of my heart that the feelings between us are real and I am willing to work hard for it. I don't want our past to be an obstacle to our future, and I don't want our relationship to end. I believe that we can go through a long journey of life together and share happiness and troubles. Please give me a chance to prove my love and commitment again. I love you forever, and nothing will change.
