Because it's Kevin I, of course, read into his public display of "I think I was just a really shitty partner. That's all there is to it. Easier to just admit that."
His replies have a bunch of "nope, it's often both people" or "sometimes it's just outside your control" which is, also of course, the expected response when you say that publicly.
Does he believe what he's saying? It's possible, he may be ruminating privately. Is he going to change his behavior? Doubtful. He's already taken the issue to a sort of nebulous "I did bad" of which the only possible future correction is to "do better" which is also not very useful to promoting specific change. Kevin has done the public display of "it's me" so everyone could say for him "it's not you" which allows Kevin to accept that since it's not him saying it. Surely the others wouldn't lie to him even though they have no information and Kevin wouldn't allow any dissent anyway. (Go on someone, try telling him it actually was his fault personally in a specific way and see how he responds if you think it won't be defensive.)
But even more one should notice as always, the narcissist move, Kevin doesn't mention the relationship or the cause of the breakup, he simply proclaims it his fault. His followers respond that it's not. So either Kevin had absolute power in the relationship, Wedge merely existed in it, and it remained in Kevin's power completely to determine the course of the relationship. Or Kevin was perfect and it was out of his hands anyway. The "third" option presented by one follower isn't actually one, it says that relationships sometimes don't work, which is both true and absolutely meaningless, but it fits the pattern of the second one where it was out of Kevin's hands, this was simply how it was going to happen. None of the options require Kevin to change his behavior. Sure, the first one seems like that but Kevin wasn't truly presenting that, he was presenting it so it could be rejected by his followers, and all he committed to was not changing his behavior but simply doing his behavior in some better form.
So as always, we should turn to our holy books containing the Ur Theory of the Modern Lolcow: Wedge proclaimed his independence in some manner, perhaps objectively correctly, Kevin turned to his followers for confirmation of his centrality in the universe to soothe the Wedge caused pain, that of the narcissist injury. Kevin has already begun the process of learning from this, further learning the importance of Kevin in all things. Inshallah.
