I apologize for my thoughtlessness. You deserve better
I am truly sorry for my thoughtlessness and the way I have treated you. You deserve so much better than the way I have been acting. I know that I have not been the best partner to you, and for that, I am deeply sorry.
I realize now that I have taken you for granted and have not shown you the love and respect that you deserve. I understand that my actions have hurt you, and I want to make things right. I want to apologize for all the times I have let you down and made you feel unappreciated.
I know that words alone cannot undo the pain I have caused you, but please know that I am truly sorry for my behavior. I want to do better and be the partner that you deserve. I want to show you how much you mean to me and how much I value our relationship.
I promise to make a conscious effort to be more thoughtful and considerate of your feelings. I want to be there for you in the way that you have always been there for me. I want to make you happy and show you how much I care about you.
I understand that trust is something that is earned, and I know that I have a lot of work to do to earn back your trust. I am willing to put in the effort and make the necessary changes to show you that I am committed to being a better partner.
I hope that you can find it in your heart to forgive me and give me another chance. I want to make things right and show you that I am capable of being the partner that you deserve. I love you, and I am truly sorry for my thoughtlessness.
