KC, quit trying to "nice" him back. It never ever never ever never ever works. You locked down the finances, that was a very wise and prudent thing to do given your deteriorating marital situation. He is pouting and throwing a fit and making all kinds of accusations like an 8 year old that wants a toy at the store. Let me ask you, would you give that kid the toy? Is that the answer? Does it make everything better? Temporarily maybe, but that kid will lose ALL RESPECT for you and continue to control and manipulate you in ever more aggressive ways.
DO NOT PAY OFF YOUR CARS RIGHT NOW. DO NOT GIVE HIM MONEY TO BUY A HOUSE. I don't care if he thinks it's "his" money that he was going to use to buy some fancy toy, it's marital assets, period. You've taken moves to protect yourself, and that is GOOD because you need protection from this a-hole.
You want to recon? Then you've GOT to earn his respect. Quit being the whiny, desperate, pathetic pushover content to lap up crumbs. Respect yourself enough to quit giving in to his manipulation tactics. Everything needs to be filtered through your attorney now, period. Stop being the victim and start being the strong woman you are inside.
