I would stay away from her as much as possible, and let HER file. If you can stand waiting that is. I would stick up for yourself and not let her get away with anything at this point.
On the other hand if you really feel that there is hope, by all means.. continue with your db/pma.. but if you don't, I wouldn't waste my time.
Only thing I would say is try to protect your kids as much as possible from her rantings.
I guess what really set me off yesterday is her using the kids like she did. She was using the kids to get what she wants.
And yes, I can wait. And I will wait. I am not going to file. The divorce will be initiated by her. As I have said, she doesn't have the guts to file. She won't do it.
