Thanks for the post, Cobra. I'll think about this. I know my oldest tells his girlfriend everything, but I don't really care about that. It's the telling things directly to their mom that bothers me. I usually stop them when they start ragging about their mom. I offer suggestions of other people they could talk to, but I tell them that, unless something dangerous or risky is going on over there, it is not really my business, and that I'm sure their mother would appreciate it if they wouldn't tell me about these kinds of things, the same way I appreciate it when they don't share non-dangerous/risky stuff with their mom.
Let me refocus the thread, here.
I have not yet sent W the email. I have an appointment with my C this afternoon, and I'm likely going to show it to him first. I thought more about the "confrontational" nature of it, and I am comfortable with its current tone.
