I've seen Nader's type do their thing before. Scummy sociopathic druggie men will stick around surprisingly long, provided that money, pussy, and material resources continue being provided to them, while the guys make only a bare minimum of effort in return. The sob stories they use to look "deep" in the beginning are just to trigger sympathy in the female so that she will provide things to him and do work such as bringing groceries for free. He doesn't care about her 20 phone calls and zillion texts because he doesn't care, period. He is there for whatever he can take. If she stops providing AC units/TVs/groceries and such, then he will ghost her. The number she has for him probably is a burner phone as others have guessed.
Chantal is being played. We may have to take bets on how long it will continue until she runs out of shit to give him.
This interpretation of Old Boy's intentions rings true when looking at the total 3 week saga as well:
1. Starting with the episode where Chantal crosses paths with the the scorned previous slampig - Chantal claimed that the woman was pissed off and called Dude a player and a user. He claimed that she was simply going to be his roommate, though he admitted they had casual sex - I am guessing that former piggy was under the impression that she was moving in with her boyfriend - I mean Chantal would think that, why not this weird lady? Perhaps she even gave him half the rent money...or hell all of it for the month, she was moving in after all in her mind!
2. The infamous TV debacle -"Oh I am sorry, we can't watch TV here, it's really a shame bc I would love to cuddle up and watch a movie"...And said TV's sketchy demise.
3. The discovery of her channel. If this man was just a weird skinny loser, he would se that and say uhhhh, no thank you. But the discovery of her channel simply lit up dollar signs in his mind. She has disposable income and is already travelling to his every time, offering groceries, offering THC products, etc. So what if she's gross and crazy, that just means she has one pseudo real life friend - good old OG simp Peetz. And if he watched any interaction between the two on her channel, he knows that jizz stain ain't gonna say boo about how Chantal spends her time or money. So she has no people in her real life to wake her dumbass up. And she has the added bonus of many, many online ass patters who will ultimately go along with whatever she says for whatever mentally ill reason they have (I won't even begin to break down her INSANE audience here. I don't have time for a full time job I don't get paid for).
Since you already went over why he wouldn't care at all if she calls/texts him like a psycho, I won't add anything there. But I definitely think that this dude sees nothing but easy access to resources of all sorts. And dumb dumb Chantal is too self-absorbed to catch on to the obvious fleece. You love to see it !!
