That's it really. After 2.5 years of stalemate and fruitless mediation, I finally agreed a financial settlement with my ex.
I'm so relieved. Much less emotional than I thought I'd be, I'm neither happy nor sad.
The settlement is better than I expected, and much better than what I was willing to accept to just get this over with for good.
For anyone out there still going through the process, hang in there. It will end.
