This is really getting old... My W just cannot speak to me w/o an attitude and acting as if I am the most horrible human being.
The fact that this is getting old for you tells me that you are beginning to detach. This is a good step. You are removing yourself from the situation and starting to see it for what it is, not just the emotions of the situation.
Also, the notice that she is still so angry and has an attitude with you tells me she is trying to bait you into reacting and being emotional again. This will give her more cause to push you away. I think you are doing well with being polite yet not totally cold. That is a VERY HARD thing to do. Remove the fact that she was the love of your life and your heart is broken. I know, again hard to do. But I see it as kind of starting over with a new friend, for both you and she have changed and if the relationship is to get better you need to approach it with a beginner's mind. Build the friendship again first, just as you might do with someone new.
I sense she is coming to grips with the reality she is creating for herself and that is making her feel guilty and angry. Let her soak in her own feelings this is good for her. As long as you remain positive and don't fall into the bait traps she sets, she will realize her own feelings within her own self.
Keep up the good work mark, you ARE making positive steps, as hard as that is to believe right now. I am there too, so I understand.
