I have one grown daughter who fits the bill. We don’t have any boundaries for her ; she lives in another state . We just hope she stays there. She is self destructive to the enth degree and there is nothing we can do about it. Each time we “help her” as she calls it with a place to live she leaves it. Whether apartment or house she leaves. And each abode is always, without question, visited by the down-and-out who drink, drug, steal and use her as much as possible. Nothing I can do about it. All, and I mean all of her high school girlfriends have turned their lives around = but not her. She lives for her yearly tax return money which lasts a week even when into the thousands of dollars. And I won’t even go into the cars she has had stolen or wrecked. My other daughter? The joy and pride of my life .
