I assume because Gary isn't as wealthy as he probably portrayed when they first met and if she wants that luxurious life, she has to hustle now.She looks so worn out and stressed these days. I don't know why because it seems like her lifestyle allows plenty of time for pampering and being spoiled (i.e hair/nail appointments, getting surprised with birkins and just being an influencer in general lol) I think she stresses herself out more than necessary, like she needs to prove that she works hard, or maybe she's just bad at handling stress. Her life could be way worse than what she shows, so I can't speak but just making an observation.
By the way, Gary's shirt in this video is $750!!! Foolish.
