I have the opposite reaction to Perna. This event happened before you were together, so her reaction seems a bit on the paranoid side. I understand that she might be hurt since the person was 'close to her' esp since I've had similar reaction to my dh but only because they still talk. Now its hard to know what her end of the story is, but I think having her move out might be better for both of you. She can prove to herself and to you that she can be on her own, and then in her own time decide if she wants to come back. Again though, therapy is her own choice. If she is not willing to do it, except that you want her to, it will not be as or any helpful. Good luck
