Pablo Neruda writes in the perspective of a hurt, rejected lover. He fuses the concepts of closeness/intimacy/romance and distance/alienation in the poem. In the same line, he quotes "I loved here, and sometimes she loved me too" (line 6) and "She loved me, sometimes I loved here too" (line 9). I believe he is writing down his feelings about how love can be saddening, decisive, and confusing. He could never decide if love was constant or love is "sometimes." Love is a constant struggle like how "love is so short, forgetting is so long" (line 28). Do you love someone...or someone else? Does she love me or have I lost her to another man?
