At least she is communicating with you. Thats a good thing. And the fact that she has not filed those divorce papers yet says that she is still unsure. Ride with it. Don't pursue her hard.
Maybe what you should do is something that you know she loves and you and the kids do it, but somehow let it slip that yall are going to do it. She might ask you if you want her to join. But its got to be something you know she loves to do. An absolute favorite restaurant, a favorite movie, a favorite event, concert, theme park, etc. Is there anything she always loves to do?
Just a suggestion since you are trying to think of ways to ask her out, but don't want to pursue to hard.
