A break-up song!

I'm not sure about this line:

It doesn't run very smoothly because naturally one expects the line to read "How do you expect this to end?" It also felt illogical to me, I can't explain why, but when a girl is using you or manipulating you etc, she doesn't think to herself, "Haha this will never end!" You tend to only think thoughts like, "This is going to end" when you're in despair, or "This is never gonna end" again in despair but implying that you wish that it would end, only it won't. I guess my main objection is the language we'd normally use based on our situation, and your language doesn't match.

How about maybe something like:
"Did you take me for a fool, thought I'd live and die for you?"

I'm not a musician and neither do I write songs, and I know my example might not fit into your meter but you get the gist

Otherwise it sounds like a nice song. If you wanted it to be deeper, I'd maybe expand on how the guy feels cheated, and I think you can add depth by expanding on just what the girl did to deserve these words so your listener can relate and therefore feel your song more. As it is, it sounds like the girl's been a darling and an angel and crying to have the guy back in the last verse and there's the narrator just being mean.

But like I said, I don't write songs and I think the depth you have here resembles the average pop song I enjoy, so it all depends on what you want for your song really.
