You mentioned that when you look at her, you see a replica of yourself. Could it be that because of the fact that you are just now beginning to recognize the things in your life you want/need to change and the things that you dislike about yourself, that seeing this is her is bothering you? I would say that you need to just take it one day at a time, and see as you grow and change in your recovery, whether she does as well. You've had a clouded mind for a long time. Things change. Sometimes for the good, sometimes not. All you can do is take the time to find out. I am sure that in time both of you will know what the right thing to do is.
