You wash your neck when you leave, now I know your routine
After a long night involving drugs, sex, and whatever else, Abel cleans himself up before leaving — implying that he routinely uses her to vent his sexual frustrations and then is gone with the wind.
Maybe he is trying to make any hickeys less noticeable? Maybe he is trying to rid the scent from the night before, or lipstick/makeup stains? Or perhaps it serves a latent function, and the washing is an effort to shake off the guilt.
