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 are spent alone
You said you would be the warmth in springtime
That was 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 would 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?
