your last post is exactly what I was going to say... she needs to hit rock bottom and see reality, no more freebies and coming home to see the kids then to party, she made her bed she has to sleep on it. You put up with way too much and gave her enough chances. There comes a time when one has to have some dignity and say enough is enough. Keep this frame on mind, you are in the right track, you did all you could but she wants to be 18 again and who knows when reality will hit her. Do NOT back down, tell her she has x days to move her stuff, do not pay anything else for her even if she is in trouble. I too got the "need time to think" and then moved in with a crazy ow, the R soured after the "magic" was gone in 5 months.
Stay strong, you are the only responsible parent the kids have right now.
