Susie,
So happy for you that you are thinking about yourself. When you think of all the time he needs to get his shxt together. It is a waste of your time. Plus years and years of always questioning the truth. It is really hard work, working a program and getting sober. If he truly does, he will realize what he lost.
I wasted 34 years (26 married) with my addict. I will be divorced 2 years at the end of October. I am doing really well, but it did take me almost 1 3/4 years to finally go no contact (June 16) . I am so glad I moved on in my life.
