I think she realizes that she has put you through a lot with her addiction. She knows how much you love her and how much her lifestyle must have hurt you. I think she finally feels like she can let go of some of the guilt she feels for hurting you. She is hoping that along with her taking charge of her recovery she also wants to make you happy.
She doesn't know how hard you have worked to detach and build a life for yourself even though she was deep in her addiction. All she remembers is the pain that she caused her family.
I say let her know that it makes you feel good to know that she is safe and taking charge of her recovery. Going to bed with that on my mind makes me sleep very well.
I think most of us moms would feel that way.
I wish Megan the best...................Lo
