Hey my love,
I write this letter to present my sincere apologies for being rude during the heated conversation that we recently had. I know that my words did hurt you a lot and must have broken your heart into pieces. It was my fault and I shouldn’t have said such words out of anger. You have been with me during the worst phase of my life and I always need you with me. I write this letter to say sorry for what I have done and I expect your forgiveness. Once again I am sorry.
