I think I posted some advice to you a long time ago and it still stands:
1. Dont attempt to counsel or mediate with your WAW. Your goal in MC should have been to not do MC. Sounds like you finally stopped doing that finally. Your goal in mediation is to make a fair offer, do not fold, and then let your L handle it. You made the right call by sending her an offer. Keep pushing this forward.
2. As for the letters and pulling over - these are non issues. Erase those from your brain and never mention or think of them again. Ever. You have written about them here about a billion times and clearly you are fixating your fears and anxiety on these events. If she brings them up in court so what. Judges are too concerned about kids who are in legitimate danger. No one but you gives a damn, and your WW doesnt give a damn either except these are super effective weapons to control you due to your insane levels of fear. She's still got you right under her thumb. I cant tell you how many times Ive seen WW's threaten BH with crap like this, the entire time laughing about it to their friends. Then 8 months later 'every other weekend dad' is back looking for custody because XWW is leaving her daughters alone with her meth-head boyfriend du jour. Your only fear should be the future welfare of your kids, and you should use that fear as motivation to move forward for their benefit instead of an excuse for cowering from your WAW.
