Literally: it should be that a woman is looking forward to her lover's return, but she doesn't know when. She can only look forward to the return of her lover every day on the only way to her return, and her sight has extended to the distant horizon. However, when she looks to the end, she can't see her lover, and she can only expect her lover to return day after day.
I hope my explanation will satisfy you.
