Lost my marriage to cocaine/crack cocaine.
It was and still is one of the hardest things for me to deal with but like you...it was necessary for my own survival. I've been officially divorced for almost a year now but he's been out of the house for much longer.
Somehow we do make it through...give yourself time to heal and keep focusing on you and your recovery from living life with an addict. There is much to recover from.
Believe me...you do eventually get to a better place.
