Dear [recipient's name]:
I really regret that argument we had yesterday and want to apologize to you for anything I said that hurt your feelings or upset you. It makes me sad to know you're sad about things. I would really like to have a long conversation so we can both get things out in the open and resolve everything. Can we do this?
You are my everything, and I want us to right any wrongs and get back to having the incredible relationship that both of us really want.
All my love,
[Signature]
