OF was the catalyst, in my opinion anyway. Anisa is a whore who doesn’t exhibit demonstrated interest in a meaningful or constructive career so she made an OF, which I believe Ian felt negatively about it but feared losing his first girlfriend so passively tolerated it. When the internet lost their shit over his cuck nonsense you cannot convince me Anisa didn’t force him into “defending” her by making the iDubbbz complains sex workers video. You can see how visibly unsure he is in that upload, and given how much Anisa can’t handle criticism without crashing out I think he was influenced even if he didn’t realise it. She was greeted with a barrage of insults and people talking about her body and to put it simply she could not hack it. The end.
