I'd say they'd been very loyal to each other. It's just they prefer to keep things private. They share most things, I don't think it's an issue. We have to remember that Dan only came out when he was 28 or something. And that's not just to the audience. He hadn't even told his family before then. So he probably just wants to keep his relationship with Phil his. He said that himself in his coming out video.Yeah tbh at this point I think they have to be together because it's the simplest answer. I'd believe they've been in an open relationship in the past, but it's been like 15 years online without so much as a whiff of either of them having a partner of any kind.
