Fair enough, but you ask the same type of question(s) and have the same thoughts. You should know by now that you should automatically not contact her so I'm sorry if I fail to see why you keep needing to vent about the same thing. and Hear us tell you the same things over and over?
Tell your 'Friend' that you do NOT, under any circumstances want to know what she and her borderline personalitied self is up to. It's not of your business and it's detrimental to you giving her up for good. I'm sure you've discussed this with your therapist as well. What does he/she think about you getting updates from your friend knowing how hearing of her or about her sets you back two paces?
