Incident 3 is sufficient to say that end is near without regrets. Incident 3 is very telling and basically shows that she is a vapid person. You should be able to do much better than that. Since incident 3 happened already, I retract the idea of talking to her about her possessiveness or trying to involve third parties to demonstrate your value in the eyes of others because it is pointless by now. She is on a path of war when she excludes you from all social events, so at this juncture your having seen the lawyer is a good step in the right direction.
