@annamom
I wrote my response and the responses of others are based on what you said transpired when you went to move in with your D.
You have not done a god job of communicating what transpired. You did not tell the whole story at the beginning and now you are in your feelings saying that people are making the wrong assumption about your situation.
Much of this situation could have been avoided if there were better more open lines of communication between your D and her roommate. I get you love your kid, but you are an enabler who is not giving her the space to work things out like a young adult.
