She is 32 yr. old and has been through rehab 5 times. I think she is old enough to take care of herself and experienced enough to know how to do it. I wouldn't take any action at this time if I were you.
I hope she does start fresh with this move.
My son is 32 yr. old (in a couple days) as well. When I read a post like yours I think "my goodness, that person is old enough to take care of themselves!" yet I must remind myself of the EXACT SAME THING when dealing w/my son. He hasn't matured with his physical age - seems more like 20ish (about the time he started using pot & eventually turned to pills).
