Sorry, that was a cross post I was reading and thinking.
Stars - what's holding you back?
Some guesses:
Fear of the unknown - you don't know where you'll be living, don't have a house to go to, its all going to be so different from now. On the positive side, you won't have the fear of what your H might do or say constantly - even when he is out I get the sense that its an overpowering influence on you which is sapping all your spirit.
Fear for your children's future - school, where you'll live, what effect it will have particularly on your son. WA must help mothers deal with this on a very regular basis. Also, I remember that you mentioned two things about your ds in the first thread - one that he was 'expecting' you to tidy the dining room up in a similar vein to that your H would impose. Another time I think he came and gave you a hug or something when H had upset you (again). This is not a healthy situation to be bringing up children in - they shouldn't see your H treating you like this, they shouldn't be subjected to potential harm from a drunk.
Fear of change - but surely this must be less than the fear of H every day?
There must be so many things rushing round your head at the moment - its not surprising that you panicked this morning.
I really hope that you don't wait another three weeks - I don't want you to be treading on eggshells for that long, I will be really worried about what your H might do. DP has made the offer of helping you move the essentials - including yourself - tomorrow, please please please think about this - this weekend you could be free and safe. But I'm sure no one will blame you if you decide to stay for a little longer.
Please take care of yourself.
