Thing is, if W had an affair or not doesn’t really matter. It’s between him and Kate. It’s NOT Harry’s secret to share.
If there was an affair - since they are still very much together and presenting as a happily married couple - then Kate has clearly made her choice and they have moved on from it. That’s her choice to make and is nobodies business except hers and Williams.
If there wasn’t an affair - a re-hashing of all the speculation will do nothing but cause distress.
Either way, like I said, it’s NOT Harry’s story to tell. He should stick to telling HIS ‘truth’ and stop crossing into other people’s lives.
He is doing the very thing he’s been protesting about, he’s no better than the tabloids at this point - saying just enough ‘nudge nudge wink wink’ but not enough to get him in trouble with the lawyers.
Regardless of the affair being true or not - What will this do other than create masses of media speculation around his brothers family? - a brother he was once so close to, and a SIL he was said was like a sister, and their young children). It will cause them deep emotional distress (their MH apparently is not important to Harry, only Harry’s MH is important to Harry - and for what? Why?
Why would you set out to deliberately try and destroy or harm people you supposedly love?
