My dearest boyfriend, I am deeply sorry for not telling you sooner about the things that have been bothering me. I regret having made you waste your precious time and for making you invest your time in a relationship that may have caused you frustration and disappointment. Please know that I sincerely apologize and genuinely feel remorse for any pain or inconvenience I may have caused you. I truly am sorry, and I hope you can find it in your heart to forgive me.
