One more thing... if and when she calls you, keep the conversation SHORT. Be polite, calm and confident. DO NOT SHOW the doubt and suspicion flying around in your mind.

If she pushes for R talk or something like that... listen, validate and avoid sharing your thoughts. Best thing is to cut it short,
"Sorry, I wish I had time to get into this but I've got to run."
"I've only got a minute before I need to report for some extra duty."
"I'm not sure how I feel about that, let me think about it and I'll get back to you." .... then don't
"I'm fine but very busy."
"I've got a lot of work to catch up on, we'll speak later..."

You're very busy. More important things to take care of at the moment. THIS IS YOUR TACK FOR THE NEXT FEW DAYS UNTIL YOU SETTLE DOWN.
