As you said, he is in early recovery. Now it is time for you to recover from all this hurt. Easy said hey? Its a hard road when all you have done is support someone and now you feel like youve been beaten around the head.
As easy as this sounds, try focussing on the positives and try not focussing on the negatives of your husband. When I put all my negative energy into bad thoughts, all it does is make me feel worse. I can ask why but there is no use in me trying analyse things I cant control or understand. I guess you need some kind of closure, so turn the page hun.
A new chapter in your life, with a beautiful daughter that you can focus on, you are young with a great life ahead of you. Its pretty damn scary to be on your own, I know, ive been there, it will get better, so keep posting all your thoughts, we understand.
