Ultimately, I do believe you will get past it. The reason I believe this is you are here. I also believe you will be able to forgive your W, once she forgives herself. The reason I make this statement is until your wife forgives herself she will not subconsiously accept your forgiveness.
She has taken responsibility, now she must decide if she is going to forgive herself, more likely though she will see if you will forgive her first. This is a critical time in your relations with her be supportive but not a doormat. Also do not be shocked or discouraged if she seems to withdraw. The owness to fix this is in her court. Also when she does feel better about admitting responsibility, she may put a full court press on to fix everything overnight.
Of course that is when you and her have to remind yourselves it takes time to heal from the hurt and some days will be good and some bad.
All in all, this is a great sign of the possibilities. If things don't work out and she doesn't forgive herself, you still will know you did everything you could to rebuild, there is should not be any guilt or shame in that.
