AS is bang on here.
She was done long before this backslide. She will and continue to look for anything to slag you with for blame. I have finally learned to shrug it off and "act as if". This took me a long time and wish I had done it sooner. These things will still bother you but less and less as you see the patterns and clarity will come that it is all not just you.
She is not having a happy birthday, you can rest assured no matter if she portrays one to you or not. Do not bake her a cake or get her anything. Not even a card. Get used to the angry and cold it will be a long time. Since May for me. My W and I have not spoken since Dec 27. Not even good mornings or hellos or thank-yous etc. I am feeling better and stronger about that now. Not that I think it is right, and is counter-intuitive but this is the process and methodology.
I know your anxiety all too well pal. Hang in there. You will do this.
