Sadly, the truth is, you don't know for certain. How many disappointments you can take is something only you can know. I admittedly had far too many false reconciliations with my H after my A. While I don't think you naive, I also think it's counterproductive to anticipate her failure in a few weeks, months, or even years.
You are allowed to have some down time and some doubts. She hurt you! And the thing about strength is, we never have it until we need it. Just because it feels like you have none doesn't necessarily mean you can't face and overcome the next hurdle, and the one after that. You've made major steps in just the last 24 hours! Don't let worry or doubt rob you of the empowerment and happiness you deserve for getting this far!
Just keep letting her prove her penitence one day at a time. I know it sounds trite, but seriously - just take it one day at a time.
You're going to be ok, my friend!
