If you're worrying about the content of your email and how she'll interpret it, you can safely cross that one off your list. Though she'll likely need more convincing and help to asuage her first impressions, you've made a positive overture and she can't argue with that.
Don't read too much into her first response when it comes either. This sort of thing is best solved face to face, and all will become clear once you two meet to "break bread".
Know that right now you're at the worst point, and it will only get better once you can meet and stop trying to second guess each other's behaviour.
I hope you'll share how this turns out.
