I haven't followed your sitch, but, basically everything that has been stated. She probably had a fight with OM, or something similar, and now she feels all her life is falling apart and no one is there for her. This may be the first of many nights similar to what you had. Let her cry to herself next time. Go to your room, if she wants to talk to you that badly, she can come to you. Don't go to her, you are feeding her the cake.
