I am a lot like you. I never figured out how to detach. Every night my W goes out, it breaks my heart. She is on a 4 day "Business trip" right now. It is a lie, she is really on vacation with some man.
She hasn't called or messaged the kids since Sunday. Somehow, she doesn't think they notice. I know how hurt I am, I can only imagine they feel the same.
I feel your pain. I am happy for you, knowing that you have a fixed time table for when this will be over. I look forward to reading posts from the new Lanzo.
