It will be only a matter of days now until her return to Kuwait, Salah will try to push her to exercise, she will do the absolute bare minimum for a couple minutes and then exclaim how ill and horrible she feels only to come back on eating pizza hut, buckets of rice and broiled chicken from the street. Then Salah will just simply give up.
With his new emphasis on her exercising and eating right "for her health," I think he's trying to push her out of his life. He needs her to leave, and he needs her to go willingly, without her going into a destructive rage in which she tries to ruin his life. She's making less and less money, and if she requires hospitalization or dies in Kuwait, it's going to be a real shitshow for him.
Overdoing the concern about her health, and upping the pressure on her to do things to improve it—"because I love you, babe"—should be enough to do it, if he can consistently keep that pressure on her until she finally bolts.
The problem is, she has nowhere to go. She can't afford Canada, and she's not going to be welcome on Shmee's couch for long. Maybe she could spend a while walrusing around in cheap, third-world hotel rooms, but at her rate of decline, that's not going to work out very well for her.
She needs to find a feeder who will let her lie around all day, provide her with endless food and THC edibles, and accept her in all her filthy, disgusting, ill-mannered glory—somebody she can willingly leave Salah for. Chantal stays in Kuwait because she has a "husband" there, and she can afford it (for now), and the only way she's going to leave voluntarily and end the torture that is the Kuwait arc is if there's some degenerate who can offer her an even better place to beeze.
So that Anime Sucks Cope and Sneed retard had better keep wooing her with $100 superchats, because I'm sick of Salah, and Kuwait, and want to see her go out in a blaze of glory, instead of this pathetic slow spiral.
