I'm so sorry. You are doing the right thing for you and your kids.
It seems like this is so common here. They want the divorce, but the LBS is often forced in to filing. In my case, my wife filed in January, but since then has done almost nothing towards finishing the divorce itself, although it's very clear she wants one. I've been doing all the work for the divorce itself. She still hasn't signed the agreement.
Now that you are filing, be prepared for the roller coaster to continue. Seeing the actual divorce proposal was quite a blow to me, and I imagine it will be another one when I actually get a divorce decree. Continue to take great care of yourself and your kids. Hang in there.
