@Batman The good news is you’re getting divorce proceedings moving. Like you say you’ll soon know either way whether she’s BSing about not being interested in assets/money etc. Either way you’ll be free to move on with your life once financial ties are broken. It will be one less worry in the back of your mind.
I can relate to bad sleep problems. I’ve tried the herbal sleeping tablets a few times for short periods and they certainly help. I share your concerns about coming to rely on them.
Sounds like you’re on the right track now, although of course tends to be ups and downs along the way. Keep going.
