It's the End of the World, as I know it--- or is it?

Sylvia Plath to Richard Sassoon (her ex) on March 6th, 1956:

This part of the woman in me, the concrete, present, immediate part, which needs the warmth of her man in bed and her man eating with her and her man thinking and communing with her soul: this part still cries to you: why, why will you not only see me and be with me while there is still this small time before those terrible and infinite years; this woman, whom I have not recognized for 23 years, whom I have scorned and denied, comes to taunt me now, when I am weakest in my terrible discovery.

For, I am committed to you, out of my own choice (although I could not know when I let myself first grow toward you that it would hurt, hurt, hurt me so eternally) and I perhaps now know, in a way I never should have known, if you made life easy and told me I could live with you (on any terms in this world, only so it would be with you)--I know now how deeply, fearfully, and totally I love you, beyond all compromise, beyond all the mental reservations I've had about you, even to this day.

.................

Four months later, she married Ted Hughes.
