I had an early reconciliation and it lasted 3 weeks before the flood gates opened....again.
My W used that exact phrase.....thinking reconciliation would be "best" for everyone. It was obvious at the time it was half hearted. She couldn't look me in the eye and say it was what she actually wanted.

You hold the cards for YOUR future. If he truly wants to make it work, it will take a long time of consistent behaviors and actions. Do what's best for you and live as if you're on your own and watch from the sidelines.
