Too me it is a negative push. If you are really dropping the rope, you simply wont care. Box it up stick it away somewhere. IF she asks, tell her.
If you try to get a reaction, which this seems to be it most like wont be the one you are seeking. Be fun, have confidance, dont care about the rest. Dont seek or call her, but be ready to lead when she does. Set up and keep your boundaries for yourself and DD. Dont escalate, just say this is how it is. end of story.
PA D laws are different then CA apparently. here only one person has to file and make paperwork happen, 6 months later your free.
