OK, I'd suggest (1) not letting on to Larla/Larlita that you know about their domestic drama but (2) to the extent that you can, welcome Larla/Larlita to your place since it might be a safe haven for her.

I hate to say it but it's interesting to read it (like really, who posts this stuff on Facebook?!) and is kind of like a trainwreck in the sense that I can't really look away. Terrible, I know.

I think you should hide her so you stop seeing this shit, and just welcome her over to hang out, for dinner, etc., as your daughter is comfortable with. That way the girl has a calm place to come sometimes.

My 13 year old's friend's parents are going through a rough time right now. Well, I am watching their marriage implode over Facebook from her mom. Saturday night was: "'Bob' (ex? husband) and 'Larlo' (son) moved out today, 'Larla' and 'Larlita' (daughters, one of which is DD's friends) are at friends' houses so it looks like I'm home alone tonight, sigh...", a few days before that it was, "I will be moving out!!! Where are some good places to live near where I'm currently at", a "How does marriage dissolution work?" post with a long string of comments about WHY she wants a marriage dissolution afterwards, lots of posts about how her parents never support her, how much she hates them and how they've never treated her right, etc. She's always been kind of a time bomb ready to go off on Facebook (ie "I just can't do this anymore!!") and dramatic, and I really feel for her daughter. It's one of DD's best friends and surprisingly, a totally normal, nice kid despite her crazy mom and possibly dad (whom I've never really met).

Is there anything I can do for her or advise my daughter to do?
