It IS hard. It hurts a lot to have to do something like that. It's counterintuitive. It FEELS like the loving thing to do is to care for them the best we can. But that is NOT the loving thing to do. The loving thing is to let her go, let her be the adult she is and sink or swim on her own. If we never allow the alcoholics and addicts in our lives to take care of themselves, they never learn that it is their job to do so. The loving thing to do is honor your boundaries and let her figure out where she is going to live.
