Aside from what you all just mentioned I could tell my EX was lying when I asked her if there was someone else when she was acting really distant after I picked her up from treatment. Bear in mind we had been broken up, yet just days before she was telling me how much she couldn't wait to come back and spend time with me. Eventually found out she left to live with someone she was in treatment with. For some reason that hurt me. Not so much that she was with someone new but that she still had to hide the facts from me and still try to manipulate me.
