Not to downplay or contradict any advice you've gotten here, because it's all been really good. But I will say:
When I finally came to my senses and realized I had to leave my now ex-husband, I tried to get all my ducks in a row first. I contacted an attorney and told her to file for sole custody ASAP. I had a little waterproof suitcase that I stored far away from our home in our backyard. I started storing evidence of financial abuse in there. I kept a journal detailing all of ex's strange behaviors.
Things kept getting worse and worse, and a month later my attorney STILL had not done a thing. All this time, I was even having sex with my ex, though the attraction was gone. In fact, I was quite disgusted with him, but didn't want to let on that I was up to something.
Things finally got so out of control that I couldn't wait for my incompetent lawyer. I had a wolf in my house and he was going to devour us all. I got the hell out of dodge.
Sometimes you can't wait even a day.
