According to this, she hasn't unfollowed anyone in the past month, unless she apparently unfollowed him before that?

Maybe they're starting a duo so they only want one social media account

The only thing that worries me is the absence of her ring in the recent pics.
Me personally, I'm not into jewelry/ rings and probably wouldn't wear a wedding ring.
She always did tho, that's why it's weird.

I hope not
