Dear Paul,
I have to tell you something very important for us. It will be better for both of us to split up. You know that our relationship was always very formal, and we didn't actually want to marry each other. I think I was only trying to satisfy my desire to be happy all these years I lived alone.
But now that my lost love, Huw, has arrived, I think we have to say goodbye. I've found my past, and that's all I want now. I'm sorry, very sorry for this.
Yours forever, goodbye,
Megan
