According to Blanche, why can't she live with Stanley? Scene Four

From the text:

BLANCHE: Stella, I can't live with him! You can, he's your husband. But how could I stay here with him, after last night, with, just those curtains between us?
STELLA: Blanche, you saw him at his worst last night
BLANCHE: On the contrary, I saw him at his best! What such a man has to offer is animal force and he gave a wonderful exhibition of that! But the only way to live with such a man is to--go to bed with him! And that's your job--not mine!
