I am not surprised that her stance is the same. She's not ready to listen to relationship talks. Do what works for you, i.e., detaching. Allow her to come to you and no more relationship talks.

Just be yourself and try to enjoy the holiday. If you invite her to attend something, do it w/o expectations. If she says no, so be it...but you go ahead and do what you have planned. When she sees that you are moving forward, then and only then, will she become curious about you, what you are doing and who may be along for the adventure.

Leave her be...allow her to come to you.

Try to enjoy the holiday as much as you can. A new year is around the corner and that means new adventures will unfold for you.

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.
