I also think that. I mean they still live in the same apartment/house. I just think they don't wanna show it that muchShort answer. No.
Longer answer, both he and saige said from the start that very little of their relationship would be shared on line. They both have busy lives so they end up hanging out with different friends at different times but having been in recent damien streams a couple of her friends hang out in his stream. She was/is freelance with smosh so for one reason or another hasent filmed with them recently.
But no, they have 100% not broken up, literally onenof the most recent photos in this thread his damien cuddling saiges cat Wednesday. Because he lives with her, because they are a couple.
I suspect that when they both hang out with friends at the same time they chose to keep those moments private.
