This song is definitely about an affair. She is struggling with the heartache of having found love but having to live without him. Also wondering how he could possibly keep up the charade at home when he tells her it is she he really wants to be with. She describes the torment of being in love with him and waiting for him when she knows he will probably never leave his wife "investing in something I'll never see". Then in the next part of the song, she describes the penance she pays for having the affair: ultimately not being able to be with him. He lets her go b/c he can't, or doesn't want to, leave his wife. She's asking if he'll keep her for a couple of reasons. One, she desperately wants him to stay with her, of course. She doesn't want it to be over. She doesn't want to lose him. Two, she's asking him to keep her memory, to keep loving her, to not forget her, b/c that would be worse than not having him; to think what they had was nothing, not even a memory, like it never happened or she never existed would hurt far worse.
