I agree with digitallove.

I think this song is about person A who likes person B, despite the fact that A knows B is not a very good person and, specifically, not good for A. A is falling for B even though B is all wrong for A and A knows it ("this one's come to tear me all apart").

A is reading B's gestures and body language ("just read those eyes, trembling lips, and carburator sighs/thighs") and can't control the crush "even though [A] know[s] they're telling lies." A wants to stop liking B and begs his/her heart to "be still."

A also notes that s/he's "grown soft" - s/he probably never stood around for the shit and lies that B is feeding A in the past, but now s/he's taking it. And the feelings A has for B are so strong; A feels B can use A whichever way s/he'd like ("cut me, smash me, strain me, eat me") - A is like apple sauce: fluid and weak, unable to be strong against B.

I think the "don't forget" part is A reminding him/herself to be strong and remember that B is full of lies, reminding him/herself to "be still."
