Unreliable

His phone gives no response; it's on vibrate,
Across the room from him; and he is sat,
Refusing to respond because it's late;
Why is he so prepared to start a spat?
He said that he would call: but it's gone ten;
I'm up much later than I sense is good:
I wish he were reliable, but then
I could not fuss or chide when I am stood
Up by the one who, it seems, does not know
How vital it is that I hear his voice;
Why can't he walk across and ring to show
He'd never let me down? It's not my choice
To be on tenterhooks; I have to wait:
I see it in my mind - still on vibrate.
