How do i write an effective apology letter?
I think that instead of apologizing once again, you should instead write a letter telling her all of the things that you find special about her. Try to reinforce the reasons that you fell in love with her in the first place. Your cheating on her likely crushed her (rightfully so), so her faith in not only you but in herself is shattered right now. Only by clearly stating how much she means to you will you actually have a chance at repairing this relationship. I also recommend that you ask yourself why you cheated on her in the first place. Be honest with yourself. If you actually love her, yet you had sex with someone else, there is something within you that you need to address ASAP. Whatever caused you to do that may rear its ugly head again, and you need to understand that for your own good.
