Hi,
Here are some words from the novel Lady Chatterley's Lover(page 42, Chapter Four) by DH Lawrence (planetebook)
(background: After having sexual intercourse with Michaelis, Connie felt their love affair was hopeless……)

Yet other men seemed to mean nothing to her. She was attached to Clifford. He wanted a good deal of her life and she gave it to him. But she wanted a good deal from the life of a man, and this Clifford did not give her; could not.

Michaelis needed(=wanted) Connie's life is because he needed her nursing and her help in writing his stories. But I don't think Connie needed a man's life. What she needed I think should be a man's love, physically and spiritually.

So how should I understand the red sentence please?
Thank you in advance
