For me, the song is about a person (let's say a she) who is in a complex situation — maybe she is in a relationship or another situation, that makes her unable to return the love, even though she somehow wants to. She doesn't want to end the relationship or situation she's in, but it still hurts because she cares so much more than she is able to show to the person. "So I think it's best we both forget before we dwell on it" — it's best that they leave it all, because if they don't, she'll give in to it.
