I think whether they have or haven’t, it’s completely the wrong attitude. I enjoy watching their dynamic as a couple as they seem(ed) to be truly happy together.
She has a lot of younger followers due to the style of her videos and if they have broken up, to just put it in the title / insta story without an explanation, it could worry a lot of those young fans and she’s leaving them guessing / wondering. If they haven’t, it’s a bit of a sick joke. I’d understand putting it as click bait title but then mention it in the video? It’s weird.
I’m going to guess they haven’t and it is CB because they seem(ed) so in love there is no way she’d be able to use it lightly in a video for views. When my bf and I broke up, I could barely tell anyone for months!
