Dear My Best Friend,
I fucked your fiancee and you DIDN'T punch me in the face? That was kind of you.
I don't deserve your forgiveness but damn I sure wish one day I may have it. Apologies and regrets are never going be enough. I screwed up, big time. And I am really, really sorry.
More important than having your forgiveness is seeing your happiness. That's all I want for you, is the life you want for yourself. With or without me.
