Hang in there brother, went thru the same shite decades ago with my 1st wife, she got the house, car and 1/4 million..................AND IT WAS WORTH EVERY PENNY! Just be the best Dad you can, and take the high road. Even when she makes you wanna choke the life outta her sorry ass, just smile and be cool (it not only drives 'em bat shite 'cause they can't get under yer skin, but everyone involved will know who the "good guy" is, ESPECIALLY your kids, remember, THEY are the innocent victims here, and it's YOUR job to be their protector.) Keep on keepin' on brother, like my Dad once told me, "If you find yourself going thru hell, KEEP GOING!" Just consider it a LARGE deposit into yer personal kharma account! And even though it doesn't seem like it now, everything happens for a reason, without the previous shitestorm, I wouldn't have met my current wife who happens to also be my best bud. (although, I wouldn't have appreciated her in my younger, DUMBER years!)
Semper Fi! :rockon
