Yikes Wet - that sounds like pain indeed!! You are D now - maybe W just needs to find herself a source of income?
I would place the focus on having a comfortable and affordable place to live yourself and making sure the kids are ok. If W can't afford the place she's in, she may need to find a new place - but none of that is your concern IMHO....
Just my 0.2pence...
