I'm gonna play the reverse card on your agreeing and disagreeing by saying I agree - and disagree!
I don't think this is Chantal's 'best life'. It's been a steady descent for her over the course of her YouTube life. I absolutely think Chantal hit her peak a few years before she began her YT channel - around the time she met Bibi. She was still grossly overweight (something like 300 lbs and that makes all her current weight loss sus because I don't really believe she's only 50 lbs from her early Bibi days weight ... she looks fatter today than when her channel started), but she had a job, a new romance that I don't doubt was pretty solid in those early days and likely some level of friends. Dare I say, at least compared to now, Chantal was kind of living a normal life.
And then she lost that job as an administrative assistant. She started her channel, gained a shit-ton of more weight. Slowly began losing her mind. Broke up with Bibi. Moved back in with Peetz ... and is now vying for the attention of a meth addict.
I think Chantal realizes Bibi was the best, and only good thing, that has ever happened to her and she doesn't have that anymore.
