Do what works for you. If she texts you, wait a bit before responding and only respond to what she is inquiring about. If you want to test the waters, the next time, ask how the trip is going and see if she'll open up a bit. If she doesn't, then you'll know not to ask again.
And...yes, you are over analyzing just a bit.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
