My dear wife, please accept my heartfelt apology with all the love and care you deserve. I never wanted to hurt you, and it pains me to know I did.
I know I made mistakes and let you down, and I genuinely regret my actions. You are the most important person in my life, and I promise to make it right.
Your happiness means everything to me, and I am sorry from the bottom of my heart for any pain I caused. Please find it in your heart to forgive me.
