I don't believe Jenn is a beard. They way he acted toward her when they were first dating, engaged, married...all the things he's done for her, said about her, how he's described her on camera, how she'd never reciprocate what he'd do/say on camera (e.g., wanting a kiss for Valentine's Day, telling her how pretty she looks, how beautiful she is, etc... and she describes him as "...comfortable") how he'd create whole vlog titles about her and how he'd cite her in the descrip, etc.
I mean, it could just be one huge masquerade, but I'm just not seeing it.
And really, why are we always circling back to if he's gay or not? Like...y'all know I'm 100% for Tattle and everyone chatting it up as they wish, but I'm not getting the ongoing fascination with that.
