I think your xw feels a tad guilty for not being there for the girls. People are most likely asking her about them and she can't tell them anything because she's not been in contact w/them. There's no way to determine if she's actually wanting to help or if there is an ulterior motive, but it's best to leave her to her own mess. The girls are old enough to decide whether they want to reach out to their mother or not.
I do hope that your D14 is okay.
Yep, your xw has distanced herself from old friends/people that she once associated w/because they will voice their opinions to her about what she's done. She doesn't want to be judged or told about her and her messy situation...but that's life...actions have consequences and she's lost the respect of many people, including her immediate family. It's very sad an I do hope that she can one day get herself together and come to realize just what she has lost.
BTW, how's the foot doing these days? Have you tossed the boot away?
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.
