I know how hard it is to be going through what you are. Papers are only papers. That's it.
If you look at it nothing has changed. I know this doesn't make sense because it seems like it's moving faster than you had expected. But you're position is still the same - you have no idea what the future holds for you. Your W is still on the same path as she has been. But believe me, she's emotionally moving around also.
She's trying to push this thing through as fast as she can because she's running on impulse energy. She's built up a head of steam in this direction and she's pushing it. My W did the same thing. Less than a week after she told me she wanted a D she had an appraiser as the house. It's now 15 months later and we still have the house. She did this in many areas.
DO NOT GIVE HER EVERYTHING! My initial response was to be nice and to roll over and give my W what she wanted in the hopes of being a nice guy would help my chances to reconcile. My family did a great job of convincing me to fight for my children and my rights.
I'm not sure how the laws are in your state, but you must go see a lawyer and find out what's legally yours.
As far as her paying you down the road for half the house - if you end up agreeing to this make sure it's done legally and on paper, with a lawyer.
Question - Why does she get the house? Why not you? How about you keep the house and you pay her half later on down the road? My W thought I would be out of the house by that Easter, she would get the house, she would get the kids, I'd pay her full child support, she would keep the kids, and she actually offered me every other weekend and one overnight a week..maybe an after school also. How generous of her...lol.
They turn into nutballs wanting everything as if you owe it to them.
I can't stress this enough - GET LEGAL COUNCIL. No if ands or buts - PERIOD. You'll be glad you did.
