Well like most liars, NO he didn’t flat out admit to cheating on Courtney. He admitted to texting Molly but lied about the content of the texts. He admitted to texting her but said it was only about meeting up at the club. Molly has said that is NOT the case.
He deleted his Twitter when Courtney &Molly confirmed it & people started to come after him. So yeah, you could say he said it...but he’s still lying about the details.

I guess you could say you have to look at the bigger picture to find the truth. He got called out for more bad behaviour and he’s trying to do damage control: admit to the act but lie about the context. No one bought it especially since Tanner was slow to catch on and blew his lie. So he’s shut down his twitter. Guilty conscience.
