What is the meaning of 'without' in the phrase "was willing to live with him without"?

Solution 1:

Well, I've found the original text in Russian. The original text says, "she didn't want to marry him, however she didn't mind living this way", ie. without changes.

Hope it helped.

Solution 2:

My interpretation of the ellipsis is:

... she did not want to marry him, but was willing to live with him without doing so.
