Never Dreamed You'd Leave in Summer

I never dreamed you'd leave in summer
I thought you would go then come back home
No, I never dreamed you'd leave in summer
And now my quiet nights will be spent alone

You said you would be the warmth in springtime
That is when you started to be cold
No, I never dreamed you'd leave in summer
And now I find myself all alone

You said you'd be the warmth in autumn
Said you'd be the one to show the way
No, I never dreamed you'd leave in summer
And now I find my love has gone away

Why didn't you stay?
