AFG, you should be proud of yourself! You handled that situation better than I would have that's for sure.
Please do get some legal counsel today.
While your H has proven himself to be the lowest dirtbag out there, he still may succumb to guilt. I currently don't work so my BF pays all of the bills plus my spending money. When I kicked him out of our house he didn't even make a peep about cutting off the financial support because he knew he was in the wrong.
If you love somebody, set them free. http://tinyurl.com/2empx2g
