He's not going to like your letter.. but he DID need to HEAR that...
He wanted you to feel SORRY for him and CODDLE his addictive behaviour... your letter told him NO...
Your letter told him to GROW UP
He's not going to reply to that... He's going to pretend he didn't hear it...
So you just keep saying that... and AVIOD talking.. this is something I learned early on.. if they don't reply its because their instincts can't process... what happens is their emotions end up bottled up and they come to a boil and his reply will come out in a rant at one point..
Be ready to WALK AWAY if he tries that...
YOu have three teenagers, this should be easy enough to deal with... Just imagine right now you have one extra...
