Ya know, I was afraid of setting dates also. I couldn't have kept to it. Seems like you are doing really well with thinking of what you will do when the time comes.
I was never going to leave that day that I left. It was new years eve 2008. We were invited to a party at "my friends" house. I told him about it, invited him to come with me, he told me "no". So I was just preparing to leave, and he called me, told me he wasn't coming home that night, that he was going to be celebrating with friends, and that I wasn't one of them !!!!!!!
This would have been the 5th or 6th time that he did not spend nye with me. I got in my car, told him that I was halfway to my friends house already, and that I wasn't coming back. I drove for 1 1/2 hours to their house, just feeling first in shock, that I was doing that, and then the calmness just took over me.
I think going to the Center for Woman is a really good idea.
