DF - Hang in there, man. It's good to hear your L is giving you helpful advice and for staying married, and is encouraging you not to escalate the process.
I see some small positives here. It's good your W isn't proceeding with a D right now. It's also good she is being much more agreeable during the parenting talks. Hopefully she needs some space to think and de-compress more than she really needs a D.
I know it's tough, but hang in there, you can do it.
