Guy loves girl (or other way) and they spend some time together, but then other one notices that he/she has been cheating quite a a long time. This totally breaks his/her heart and it feels he/she cannot love anyone anymore. He/she then hates cheater very much because he/she suffered a lot from that.
Obviously this song is about:
