I am writing to apologize for my recent unfavorable behavior. I understand that my actions have caused you distress and I am truly sorry for that.
I want to take this opportunity to explain why my behavior was so inappropriate. I have been dealing with a lot of stress lately and I allowed my emotions to get the better of me. I realize now that this was wrong and I should have handled the situation differently.
I understand that my actions have caused you pain and I want to make it up to you. I am willing to do whatever it takes to make things right. I am willing to put in the time and effort to make amends and to rebuild our relationship.
I am sorry for the way I have acted and I am committed to changing my behavior. I will work hard to ensure that I am more mindful of my words and actions in the future. I will strive to be more understanding and considerate of the feelings of others.
Again, I apologize for my unacceptable behavior and I am committed to making things right. I hope that you can accept my apology and find it in your heart to forgive me.
