I doubt you are the sort of parent a child would feel the need to go no contact with in the first place.
My own Mother threw a strop when I cut contact with her, played the victim, told everyone she could that I was obviously undergoing some sort of crisis and acting irrationally.
Aside from the fact that my decision was driven entirely by her behaviours, and aside from the fact that the only one of us who ever tried to maintain any sort of contact was me, the truth is that in 35+ years since I left the parental home, not once did she make any effort at all to contact me or ask about my wellbeing. It was always the other way around despite the fact she always knew where I was, had an open line of communication, and had the means to visit any time she liked.
Does that sound like the sort of parent who could credibly claim to be "heartbroken" because their child took the decision to remove them from their life completely?
In many cases the entire reason for the child opting for NC is precisely because the parent doesn't care one iota, or they make a pretence of caring but in reality it's purely for the purpose of constructing some sort of narcissistic "poor me" narrative, so any interest they do take is invariably toxic and harmful.
From my limited knowledge of BB he does come across as a twit, but I'm far more familiar with his parents and both of them come across as awful people. This doesn't surprise me in the slightest.
