His letter was such a huge step. Don't be hard on yourself. You are ALLOWED to feel pain and hurt from watching your baby go through this (and they will always be our babies.)
Look into treatments. Leave no stone unturned. Tell him you are doing this and you will help him get into treatment. It's not too late. My husband was a meth user for many years and he has been clean over a year now and shows no interest or sign of returning. I know it's still a tightrope to walk, the waiting and wondering, but health and recovery is possible.
MANY many blessings and hugs to you both.
