Edith Nesbit - Incompatibilities

If you loved me I could trust you to your fancy's furthest bound
While the sun shone and the wind blew, and the world went round,
To the utmost of the meshes of the devil's strongest net . . .
If you loved me, if you loved me--but you do not love me yet!

I love you--and I cannot trust you further than the door!
But winds and worlds and seasons change, and you will love me more
And more--until I trust you, dear, as women do trust men -
I shall trust you, I shall trust you, but I shall not love you then!
