I love you very much. I am deeply in love with you and no one can change my love for you, and no one means no one. You are the true and unconditional love in my heart, and I can't even think of living without you. You are my angel, you are the one ray of hope in my life. I don't think it's possible for me to live without you. Even the thought of living without you makes me uncomfortable.
But I don't know what has happened to you. You are not behaving the way you used to. Now whatever I say, you think I am lying. I just want to tell you now that what you're thinking is completely wrong. I am not that kind of a guy. You think that I am after someone else, but this is not true. I know you will say that you will not ever leave me, but I want to see you act like you did before, my sweet babe.
And please forgive me for all the hurt that I have caused you. Please, I beg of you to forgive me and come back to me. I love you, and I always will, until the day that I die. Hopefully, when that day comes, I will still have you by my side and you will be the last face that I see. I will be able to hold you in my arms one last time, and tell you how much I love you and how much you really mean to me.
Please try to understand my feelings; You are the only one for whom I would ever stop a bullet--yes, even sacrifice my life. Please understand this, and please come back to me as you were before.
If you still think that I am lying, if you still do not believe me, then throw this letter out through the window and just give me a call on my cell phone. I promise I won't ask you the details of why you would do this to me. If you think that I am true and my feelings for you are true, then just open your front door. I'll be standing there, waiting for you to give me hugs and kisses the way you did before.
