Facebook is the modern Dear Diary. Just because she posted it does not make it true. If it were me, I'd bring it up in a relaxed conversation, not confrontational , only because I'd fear walking on egg shells. If this is something she's always done, part of her lifestyle, then there's nothing you can do but let her know you know and cannot risk what little you have to enable her behavior. I have a dear friend whom still does this, grew up getting everything she wanted. When the real world pressed in with a husband and two small children, her accesses became emotional blankies, even when everything crumbled. It wasn't that she never learned to separate value over materialistic stuff, but peace found in the present moment without feeling that restlessness. She held a job, was a hard worker, loved her family, great housekeeper, but emotionally she's very, very needy. It started to change when she lost everything and moved away from her mom whom enabled her to start to find that confidence. She still longs for the LV's (has three!) but because she is being held accountable...she's learning that happiness isn't found in how much you spend, but what you do with the precious gift of time. And because there's no knee jerk of guilt spending money as a substitute for other things, she's teaching better values to her children in honoring obligations, and they actually are being creative in exploring life without being dependant on Disney big ticket attitudes of entertainment.Be honest, be loving.
