You just can not make such final decisions and disappear.
I have just left my wife. She thinks I suddenly made a final decision and just disappeared. I thought I was trying to get through to her for about 2 years that we could not possibly carry on as we were. I thought I'd said everything that could possibly be said and that it could hardly be a surprise when I announced I was going. She felt very differently.
We may be able to have the conversation at some point in the future when we are both actually listening, but I am not hugely tolerant of having it over and over again at the moment when she will not or cannot listen, or believe what she is hearing and I cannot believe she only just realised that I had been desperate for ages.
