Bones is most likely talking about a past friend (man or women). Not necessarily a failed relationship but a forgotten one. He could also be talking about himself (in 3rd person) through someone elses eyes.
[Verse]
I've been working on myself, I just hope it's not too late
I just hope that you can see a difference in me
If you're running short of air, if you need, I will be there
I will breathe into you
I've been working on myself, I just hope it's not too late
I just hope that you can see a difference in me
If you're running short of air, if you need, I will be there
I will breathe into you
