If she talked about leavin, I wasn't listenin
If she showed me a sign, well I never saw
Did she stop believin, did I stop givin
Can't put my finger on what went wrong
Now the quietest noise I'm told
Is the sound of letting go
The singer is stating that he couldn't see any of the signs of her love for him fading, if she even gave any signs at all. It shows desperation in the sense that he does not know what he did or even what's going on. She could've given up on him long before hand, and he never would have figured that out. But, then again, when I went through a very recent break-up, I knew it was nearing the end. But I still fought for her, and I'm proud that I did.
