Jacob is Jacob Holm. He's from Chicago and was a high school wrestler the same time Dylan was I think but at different schools(someone correct me if I'm wrong) Bare with me I'm trying to cram a lot of material in.
Anyway while Dylan was dating Jackson he went back home to Chicago for the holidays. Jackson was actually supposed to come visit him a day before Dylan was filmed in bed shirtless with Jacob. I'll post the video bellow. When this video was posted on Messy Monday Dylan's excuse was that he was trying to help Jacob make his ex bf jealous but what he failed to mention was that he was also trying to fuck Jacob that night as well. Also I was told by someone who knows Jacob that there was another video or two that were never posted of Dylan and Jacob play fighting and cuddling in bed. Dylan was cheating on Jackson a day before he was due to arrive in Chicago
You have to remember that a couple of months before Dylan snuck a gay pornstar named Joey Mills into the apartment he shared with Jackson one day after Jackson left town, there is video evidence of Dylan with Joey at a party and also pictures of Joey riding the subway to go with Dylan to his big photoshoot. If you read the text messages Jacob leaked you will know that Dylan was basically trying to set up a week long orgy of sex with Jacob and Joey Mills while Jackson was out of town. Jackson didn't know about any of this. When fans told Jackson what was happening younow he was totally caught off guard and didn't know about it. In the Younow video at 9:35 seconds is when Jackson first finds out about Dylan cheating with Joey and then again at 17:25 he screenshots and is visibly disturbed to learn that not only is he being cheated on but Dylan took his hookup pornstar to his big time NYT photo shoot. That's like finding out from fans that your husband took his mistress to the Oscars while you were away filming
Sorry for the long post but some people are totally new to this whole Dylan, Jackson, constant cheating mess.
