It's too bad that Becky's brief reunion with family, away from the influence of her manipulative partner, did NOT result in a change of heart when she got home. How little she must love herself to remain in a situation in which she's expected to carry 100% of the burden of a "relationship" with a 600 lb troll that gives nothing in return.
Becky may be technically unemployed in a conventional sense, but Amber is a full-time job with no benefits. No emotional support, no real love or meaningful connection, definitely zero sex or intimacy of any kind. Honestly, they don't even seem like they would be friends in any other context. They have nothing in common besides an unhealthy relationship with food and a total absence of intellectual curiosity about their world.
Amber's impulse to lie about everything is so pathological in nature, that you have to wonder how Becky can see that and still trust a single thing out of her mouth. If I saw how EASY it was for my partner to embrace dishonesty the way ALR does, there would be SIRENS going off. And yes, I totally understand the illogical pull that codependency can have and the willful denial that keeps people in bad situations for far too long. But this is some next-level shit.
Becky's either gonna wake up one day, after cleaning and powdering Amber's yeasty folds for the millionth time, and decide "No More." Or she's gonna let this dumpster fire consume her very soul. Both will be painful, but the former could lead somewhere positive (like finding love and a new beginning with someone that's NOT a sociopath and doesn't regularly humiliate her in front of 128,000 internet strangers).
I'm not optimistic, but she does have a choice here.
