I agree that this song is about an unsuccessful relationship. The reason I think so is.
He is talking about taking water from his well and he cries out for moisture. Its safe to assume that water and moisture represent life. The lady in question sucked life out of him so to speak.
Most likely she used him, because he says “Why did you take
And drag me through your hell”
No intention of living this way, no intention of living
