She has always referred to Peetz as her ex-. In fact, it is in the title of the first video he appeared in. I don't think she ever called him "a close friend" except as an aside.
I agree that it is because she wants to put across a message: not only is she desirable enough to have an ex- along with her loving current boyfriend (who brings her a petite-size tribal gown from Africa, he loves her so much), but also she is so irresistible that the ex- has to remain in her orbit forever.
It is hilarious how badly she treats him, although as an Omega Cuck, he ought to be used to it by now. He is like her little trained monkey. "Go on, tell the audience what you think" she goads him. Her autistic ex- gladly obliges while she rolls her eyes and seems utterly unable to comprehend anything he talks about. She gets to be the boss in that relationship, which is all she wants. I don't think Bibi or anyone else in her life gives her such license.
I don't agree with the speculation that they are engaging in any sexual hijinx. For one thing, Chantal is pathologically incapable of keeping her fat yap shut. She would not be able to resist dropping double entendres and such, to get across the point that a man wants her enough to steal her away from her cold, uncaring (see what I did there?) boyfriend, Bibi...
In the livestream from last week, right before she chimped out, she said, "Peetz and I will never date again. For one thing, we just don't want to bone each other" While it is foolish to ever take her at her word, this is one time that I do. Frankly, I don't think she has "boned" anyone in years, and even back then it was rare (her ridiculous lolcow stories of fucking strangers and shitting on them or their walls are bogus; even she hinted that they were made up in the same livestream, which I am paraphrasing, but closely: "So what if they're not true? They're good stories!")
Peetz is not enough of a playa to put the moves on Chantal; I get the distinct feeling from him that he both likes her but is a little grossed out by her simultaneously. I doubt he has any other friends, especially men, to hang out with. She needs someone who will tolerate her gluttony and who she can be the Alpha with, and he just needs anyone to talk to between comic books. I know other pairs of friends like that, although more usually they are same-sex friendships. However, male-female friendships like theirs exist too.
If only we knew what really happened with Bibi's "trip", we would have the key to solve most of the mysteries about Chantal. Everything else about her reads like an open book, but she has sufficiently murked up the water with lies and diversions about Bibi that we probably will never get to the bottom of it. I feel like smacking her every time she says "Bibi's sister", to whom she has cryptically alluded for six months now, despite no evidence whatsoever that she even exists beyond a Facebook page. She has claimed that she went back to Africa, that she is living with them now, and that she lives nearby and visit on weekends, and keeps cycling through those stories. She went off her rocker about the time of Bibi's trip, and has never really been the same ever since. I wonder if Peetz knows the real story...
