No expectations helps from getting emotional. Nothing has to be decided. When in doubt, "I need some time to think about that."
Avoid using "you" statements and listen to see if she uses them on you (mind-reading or blaming).
Be totally prepared. Have a story to tell her to relax things. What will you wear? Show up after her, how will you approach her? Where will you sit? New shirt, cologne, be the first to leave. You be in control of you.
