There's something I really enjoyed about having my finances back totally under my own control. Even though I, like you, was already the money manager in the house, it's nice to know what I'm working with and not having to worry about being derailed by erratic or impulsive decisions by the ex.
Check out the Mr Money Moustache blog. Good food for thought, even though I'm not that frugal at present, it's inspiring and gets me to think outside the box. (And it's clear that I COULD retire now if I chose to; I don't because I enjoy my work and want to be in a position to help my kids a bit. But it's a good feeling to know I have options.)
