My two cents. I really hope your husband stays with his sobriety. I am 37 years old and have done drugs and drank since I was 13. I realize my story is dif. then his and yours. But, I have been good at staying off both for up to a year at a time. I always find myself crawling back to them. I can tell everyone around me or even my husband that I am done with it but, guess what??? I always go back.
I am finally to the point in my life that I have turned a corner and no longer want it and I am struggiling. Because, the worse part is my husband and most everyone around me enables me. They know I have a problem but, in the end they enable me. I am now facing doing this mostly alone ( sobriety ) because, in their minds they love me sooooo much and its so much easier to deal with the drunk / drugged me then the sober me, they just want me to be happy and do what I have convinced them and they have convinced themselves will make me happy.
Wow. I hope that is understandle and that I make a little sense.
