That's really all you can do is cut her off. I had a friend who got too far into it, well, she is still there. The reason why she will never see a problem with her ways is because her family caters to her. She lost her kids, her husband, her job, everything. What does her family do? Make sure she can still see her kids, pays for everything for her (NEW cell phones, apartments, cars, new clothes, hair done), she never struggles. Of course an addict is going to continue to be an addict when it's an extremely comfortable living situation.
