That is a very good idea. There is no reason to rush into anything unless your H initiates a filing. For now though focus on you and your children. And yes, it all sucks but eventually it will suck less.
Today is the two year anniversary of the day my H woke up and announced to me we were getting divorced. The past two years have been a legal, financial, emotional and physical health nightmare for me. But I am okay. And you will be okay too because you are working on becoming okay.
I agree that is very hard to trust your own judgement in this situation. That is why I am a big proponent of using an attny. There was a time in the thick of my situation I would have just about agreed to anything my H wanted just to make it all go away. That is not rational but when you are that emotionally destroyed it sometimes seems like a very good idea.
Get some rest, give yourself a "brain vacation" and try and recharge. It will all be okay one day. I know it doesn't seem like it. Not every day is okay for me but I am learning the "okay days" do exist.
