She'd have been banished from Eden without him like Lilith was before her. Lilith, Adam's first wife, has been edited out of the Christian bible, but she exists in Jewish scriptures, which the Bible is derived from. God created man and woman, Adam and Lilith, at the same time. Lilith saw herself as Adam's equal. When they got into a dispute about naming animals, God said Adam had authority over her, but she refused to bend to his will, so she was cast out of Eden and then God created a helpmate for Adam from Adam's rib, which is when we get Eve.
