Oh, little misunderstanding:
I will not show him the letter!!!!
I just gotta write it for myself to get my head and heart clear. And to maybe also be clear concerning what I really do love about him. And then be able to express that in a subtle way through little compliments etc.
And I guess the letter to myself is to get clear why I am lovable and intensify these aspects of my life. Or find out what is missing or what went wrong so I can work on the losses/deficites.
