Wow MF- I'm so sorry he put your whole family through that.
I'm wondering the same as Bobbi Jo- Can you still file and serve him, and beat him to the punch? It may still come as a shock to him that you aren't as naive and unaware as he thinks you are...
Take care, and keep being strong for your kids (and I have a great pair of spiky stilettos to add to the kicking if you need extras...)
