She said I should call her when I can "make time for us". Should I bother at this point?

Sounds like she’s done.

If you're asking the question, then the answer should be no

If you love her the answer would be clear?
I would say even asking this question indicates possibly that you may have checked out of the situation.

Obviously she’s not a priority so do her a favor and don’t bother.

If you need to ask, no.

Do bother to end it like a gentleman.
Do not attempt a “ghost”. It’s for the weak.

Yep, "I've got thirty seconds to say we are done, now you have 10 seconds to talk. Ok bye" click

If you don't already know this answer it is best to leave it be.
