That took a lot of courage, but you did the right thing. While I doubt you feel good right now, you should be proud of yourself and realize how much strength you have. Probably strength you did not know you had.
No one knows what your W will choose to do, but, regardless, the path you have taken is the one of recovery for YOU. You can only improve from here. Either she comes along for the ride under a new set of rules or she does not, and then the problem is really with her.
Stay busy, focus on improving yourself and let whatever else may happen just happen. You KNOW where you're going. I doubt she does.
