That is a strong possibility. It doesn't solve the problem with the line; to make sense, it should say she's said goodbye too many times before.
> It sounds clear to me: the girl has previously tried to break up many times, so now he is breaking up with her.
That is not so strong; the first verse is phrased in a way that suggests she is leaving him, not the other way around:
I was so high, I did not recognize
The fire burning in her eyes
The chaos that controlled my mind
Whispered goodbye as she got on a plane
Never to return again but always in my heart, oh
(On first impression, I assumed this verse meant that the girl was dead, but she could just be leaving.)
