Here the speaker looks back on a relationship that ended badly, and she doesn't let herself off the hook. The first line says the love was burned "at the stake," an image of punishment, as if the couple was put on trial and destroyed. Then comes a twist on the Garden of Eden story: he was Adam, and she was the snake. She casts herself as the one who tempted and ruined things, though the poem leaves open whether she truly believes that or is just blaming herself.
The last two lines step back into a blunt lesson. Love "entraps" you while it lasts, and when it ends it "snaps" you. The rhyme of "entraps" and "snaps" makes the warning feel quick and sharp, almost like a saying. The mood is bitter, regretful, and a little defiant. Short lines and tight rhymes keep it compact, which suits a feeling of pain that is messy underneath but boiled down into a few hard words.
