Is there a chance she'll come back again?

My girlfriend (23) cheated on me in September and broke up with me because she fell in love with the person she cheated with. They still haven’t officially gotten together, but they’re in a situationship, and my ex is hopeful that things will work out between them.

Since the breakup, we’ve met almost every week, either because she reached out or I did. When we meet, we usually talk, go for coffee, or grab something to eat.

This is the third time she has broken up with me. Each time, after her "hoe phase" or when things didn’t work out with the person she left me for, she came back to me.

Is there a chance she’ll come back again? I just can’t be without her. I love her so much, and I miss her terribly.
