if you go, do let me know" very effectively illustrates the callous and willful ignorance these abusers display towards the damage inflicted upon their victims. As if the victim were going away on a vacation, and not into the painful abyss of the mind of a damaged child. These abusers just don't get it.
I like to imagine the last verses are the victim switches roles back into that of the abused and has had the abuser jailed and then being just as callous by saying: "If you go, do let me know..." Only Dillon herself can verify this, but she seems to let everyone wrongly assume it's about a miscarriage she had, which is a preposterous notion.
