Ex best friend ghosted me for about 2 years while abroad, said she would try to be a better friend, reached out today after months of no contact again, do I give her another chance?

My ex best friend ghosted me for about 2 years while abroad, been back for the past few years. I had told her how she hurt me and that I dont see our friendship the same anymore. It's been about 3-4 years or so that she's back.

She said she would try harder to be a friend but hasnt reached out much (at best we saw each other 3 times a year) & most of the time leaves me on seen whenever I text her (same as while abroad). I stopped trying and no longer feel close to her. She's a wound in my chest and I've been grieving our friendship for the past few years through her silence. She only reach out whenever SHE wants to plan something or ask something. She reached out today and idk what to do.

I just feel tired of this. She's no longer part of my life and we've been so close before that I cant put her in the "not so close but still friends" box. I just cant and I dont see why we should keep seeing each other when she magically feels like it. She doesnt ask about me either and I feel like her mom whom I barely see is closer to me than her... We used to hang out all the time went to school and uni together, confided to each other our secrets. Now she lives her life to the fullest good for her but Im clearly not a part of it anymore.
