I agree. He's liable for half no matter what state you're in.
He's just trying to scare you.
He's either very immature or emotionally involved with OW.
Either way. It doesnt matter. All you can do is MOVE ON... and PROTECT YOURSELF... Time to take back CONTROL. Give him what he wants. Seperate accounts. Go dark.
I am dark. Very very dark. He paid the mortgage the day after I paid it. I felt like calling him or sending an email that said "Hey stupid, if you talked to me, we wouldn't have to pay our attorneys $250 an hour to sort this stuff out, AND you wouldn't have paid the mortgage the day after I paid it". But of course, I didn't contact him. I haven't contacted him since I got that ugly bullying email. I didn't even respond to that.
