I can't say you're "wrong" to feel however you feel. All I can say, as someone who has been in two marriages to alcoholics, and is almost seven years sober myself, is that the way she is behaving is like someone who is grabbing recovery with both hands, and is happy and excited about it. That's one of the best predictors there is for her ultimate successful recovery.
Now, you can go ahead and keep feeding those feelings of anger and bitterness that you have (which doesn't seem like a promising path to eventual happiness), or you can work on dealing with the reasons you feel this way (and just a hint, only part of it has to do with her) and do a little self-nurturing.
She's not going to be the way she's acting right now forever. Pink clouds fade and life--including family life--will eventually find its place in her consciousness. But right now she's doing what she needs to do, and there are things you could be doing for yourself in the meantime. Your choice, though.
