dont send it. write it for yourself, but never send it. she's not worth it. there's nothing wrong with it, but its not something you should send.
i can understand that you feel as if she were condescending, but as an outsider, i didnt read it that way. she was very matter of fact, almost unemotional. she's not the issue here.
you sound much better today. again, give it a couple more days, and keep breathing.
it is old stuff. remember that.
but the lying is hurtful, and needs to be addressed.
i'm speculating when this first started, he was lying as self-preservation, he made a mistake and knew it. then he had to keep lying as to not damage what little trust you had for him, since you were out the door. and now that he's caught, again, he may come clean on everything. thats something for MC to discuss.
in my estimation, he has lots of maturing to do. i'd say growing up, he was conditioned to get out of situations in the easiest, quickest way possible hoping it would never backfire.
Theres a balance you need to find, and it will be difficult. He needs to come clean, even if you already know everything. and you need to let him come clean. if the consequences are too harsh, (although depending on the facts it may be fully justified) he may just continue to lie. but he has to understand that lying also not acceptable.
does that make sense?
