I got to the point where I knew I'd had enough and was ready to do whatever I had to in order to physically separate from him. Before that, I'd vacillate and give myself reasons to stick around (not enough money, it's not THAT bad, 'til death do us part, it will be a huge pain in the a$$, etc...). I had to come to the conclusion that he was unlikely to change and I couldn't stand the thought of living in that situation any longer.
