DS,
You are still an inspiration to me.
I do think removing yourself from your husband for awhile may help you regain some emotional strength and sobriety. I know I could never stop drinking if I was around someone who was not sober. That, combined with the cheating and lying, would make me take a real long break away to see what the best path would be for ME.
I hope you do what will make YOU happy, sober and healthy.
You have done great and can do it again
