can I, can you?

Can I? You might close your eyes and turn away, Yet I'll still watch, a million ways. You might let go, your hands untied, But I'll hold on till the very tide. You might leave me at the altar bare, Yet I'll await, bound by despair. Can you? You might never wish to see me more, But a teardrop on my deathbed floor Is all I ask—nothing more.
