Thank you all for all of your support. My husband and I have decided that we are going to tell him that he needs to return the key that he has to our house and find a new place to live. I really appreciate all of your support, as this is really, really hard on me.

Even as I write this, I am crying, because although I know it is the right decision, he is my little brother, and I love him.
Thank you again!
