Been AWOL for abit but have stayed up with your sitch. Man the rollercoaster has been traveling at full speed. W is all over the board, you sound as though you are dealing with it in a good way. From wanting a new relationship to filling out paperwork as Mike said if the paperwork arrives sign it and give it back, don't react but act of your own accord, it's just paper. Don't try and read her mind it will just make you crazy, at this point she can't even read her own mind.
I was very sorry to read about your mom, hope she is doing better. In the book it says to try different things take a step back and interpert the reactions, find what works and what doesn't. This is not a science it is a guide in which to go by. Keep working on yourself and spending time with the kiddos and GALing.
If W asks you to do something and you have nothing planned do it Tink is spot on with this, just don't always be readily available. It's a contridication in terms and hard to understand at times but sometimes you must 'feel' your way. Observe what is working and what isn't that is the course brother. Will check in later have a great weekend...
