I'm pretty good at being patient, but your xw....well her response to your email just made me want to smack her. So, in other words, it sounds like she's not going to mail you the documents.
Yes, narcissism does come out fully in MLC. Remember, child exhibit this when they are little. Some of them walk around say "mine" when interacting with others. MLCers are very self-centered and selfish 100% and always want to look the best to their public so that they are perceived to others as being great.
I'm truly sorry she's still acting the way she is. I had hoped that by seeing a therapist she would be further along...but she's one stubborn lady and it may take a while, if not forever. She is missing out on so much w/her girls. Such a shame!
Please take care of yourself and those lovely young ladies.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
