Mojo, honey, don't read any more of his letters. Nothing good can come of it. Simply throw them in the trash. Period. There isn't one good reason in the world for you to read them.
If you're afraid there might be some actual information in them that you may need, then ask someone else to read them for the purpose of identifying any real content, but NOT to tell you anything else.
I mean it. Don't read them. Not good for you. They're all lies told from his warped pov.
