I believe, the meaning behind this song is, a guy has a girlfriend, he loves her, but all she wants from him is sex, not for love but for her own pleasure. The guy doesn't want to lose her, so he tries a relationship built on sexual activity, but it fails. He cannot keep up with it at all, he tries but he can't, because he can't do it, she gets annoyed and decides to openly admit she is going to have sex with another man. This kills him inside, he loves her deeply and when she doesn't love him back, it kills him, it kills him more to see she has left him. This makes him sick to think he could not keep up with her ('my stomach is sick'), and he blames himself ('but its just the price I pay'). He has visions that she and this other guy are getting it on, and it hurts him ('I just can't look its killing'), he knows what she is like in bed and it kills him to think she is doing it with another guy.
In summery, this is about when we as humans find true love, and it turns its back on us. It can have an awful affect on us, as if we were dying from a painful illness. This is my understanding of the song, thank you for reading.
