I think I would turn the tables and ask her if she wants to talk about anything and that you will be more than happy to listen. If she brings up relationship talks, you can always change the subject, say you have something to do or run an errand. No one is saying that you have to stay there and listen to a bunch of BS, if that she starts dishing up.
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.
