A Great Person and Valuable Friend - Your Partner
First - I want to say sorry to your partner.
I deeply regret our last interaction in-person together, I created a horrible experience for you and I feel shameful for it.
I commend you for being the better person - if we flip the situation, I know I would have killed me on the spot. I understand what I horrible thing I did to you.
You show greater patience than I have. I appreciate that you were so nice to me and my partner.
I am sorry and I would like to make it up to you however I can.
Great Person, you chose a great partner to be with and I appreciate them more and more through your path and challenges in life. I see they protect you, appreciate you, and love you.
You have an awesome partner.
