A wonderful friend to have for support.This poem came to mind when you say love should not hurt. I understand the level you are speaking of. Here is love at the mystical level.

For even as love crowns you so shall he crucify you. Even as he is for your growth so is he for your pruning.

Even as he ascends to your height and caresses your tenderest branches that quiver in the sun,

So shall he descend to your roots and shake them in their clinging to the earth.

Like sheaves of corn he gathers you unto himself

He threshes you to make your naked.

He sifts you to free you from your husks.

He grinds you to whiteness.

He kneads you until you are pliant;

And then he assigns you to his sacred fire, that you may become sacred bread for God’s sacred feast.--Kahlil Gibran
