Detach here... look at this as a business split and protect yourself. (I would get statements from all your accounts for this past year) When I was going through all this I found out W had emptied all the accounts ... one I never knew we had ... that was not a shock as she did all the bills, I trusted her completely. I went to the bank to open my own account and asked for print outs ... the teller asked me "For all 4 accounts?" (I knew of 3) So I said sure. Turns out it was a considerable sum. Here was the thing, when we were going through mediation, I did not get nasty, but I was firm .. 50-50 was fair and I was not settling for .05% less. The fact W agreed on the separation date in Dec13 allowed me to go after ... yup ... 50% of all that money she pulled out of the accounts, and I had the statements and her siggy on the withdrawl.
Even now, in my mind this money is still owed back to me. We are working on our M , but I will never give up my account nor my money ... I will transfer my share into the account and that's that ... lesson learned.
Protect yourself, emotions or not .. its a bad business deal at this time and you have to stand up for yourself.
