Tad, the early anniversaries hurt tremendously. However, this year, divorced and nearly six years on, I actually forgot mine. I loved my h deeply [and a bit of me still does] but truly it gets better. I noted the date, but just didn't register that it was my anniversary until the next day.
I don't know whether you noted in Antonia's post her xh's typical MLC behaviour in failing to take responsibility and being a victim essentially his message was that 'whatever I do I can't win with you' Passive aggressive carried to the nth degree.
Short message: do not contact your wife, respond briefly if she initiates, you will feel bad, it does get better, eventually. Oh, and you are doing well. Hugs
