No vise. You don't need to ask her for a second chance you need to back off and GAL. She's not thinking about you right now, she's not wanting to be in a relationship with you and your still clinging to her and showing her you will always be there for her. She's talking to her friends about hooking up with the beat man at that wedding and you ask her if she wants to go to a Christmas party? How is it that you know all of this btw?

If she is crying about something she feels you can validate her feelings and show you do care (don't just act indifferent, but don't jump to comfort her either). It's likely a manipulation trick but you still need to respond I'm the right way and not ignore it/be cold to it/etc. You can be strong and confident while validating her and still avoiding needy clingy.

Accept what is, let go of what was, and have faith in what will be
