With all due respect, she had a fiancé, she had her "rock," Bibi, she's (allegedly, lol) has had many lovers and the chance to have her own spawn, what makes you think the next poor sod that gets sucked into her orbit is going to magically change her?
Love means nothing to Chantal. She's a black hole that absorbs all love and motivation and sharts jealousy and hatred all over YouTube. Just look at the state Bibi was in when he finally kicked her to the curb; he'd completely lost his spark, his energy, and sat around watching animu, playing vidya games and constantly working all day to get as far away from her as humanly possible.
Peetz is heading exactly the same way because of her soul-destroying personality, and if he had any self-respect he'd get out of that luxury chateau while he still can, before he's obligated to be Chinny's full-time carer.
As for showering and taking care of herself more often? Lol, no she wouldn't. Her physical and mental state took a plunge when she was with Bibi. She got comfortable with him and just said fuck it because she no longer had to lure anyone in with her catfish photoshop jobs and sickly sweet baby voice. I'd argue that she puts more effort into her social media appearance ("effort" as in Chantal's meager levels of effort) when not in a relationship to pretend that she is oh so desirable and look what you losers are missing out on!
And as far as sex goes - in her current state? Her lungs would collapse in on themselves.
Chantal has no need for true love and a family nor does she want one. All she wants are some orbiters to kiss her ass and tell her how it's the world's fault she's the way she is so that she can dodge any and all accountability. People are merely pawns to get her closer to her ultimate goal - attention and food.
After all, what is love when you can order an Arby's Beef 'n' Cheddar?
