You lost me

I am done, smoking gun
We've lost it all, the love is gone
And we had magic
And this is tragic
I feel like our world's been infected
And somehow you left me neglected
We've found our lives been changed
And we tried, oh how we cried
We lost ourselves, the love has died
And though we tried you can't deny
We're left as shells, we lost the fight.

but it's too late
