She is in love with someone who is deeply troubled. People tell her to leave, for her own good, but she can't turn her back on him. He needs her, she needs him, neither of them leave, "he won't go, he can't do it on his own," just like "[she] won't go, can't do it on [her] own." They both know it is love, and are hoping that it will prevail over the challenges the world puts in front of them.
