Why, well because you DO HAVE expectations from this e-mail. You EXPECT him to read it. This is what I call the hidden expectations and they are the worst of the worst of expectations. If it's really just for you well then it wouldn't matter would it?
You need to step back a bit and remember and accept the fact that you aren't in control. You can't control whether or not he reads it, deletes it or even opens it.
If we really want to love, we must learn how to forgive. - Mother Theresa
