I don't think Tati was crying about a teenage, but hurt that someone her and her husband had invested time to mentor had become this person.If what James has done is true, then it is really appalling but there is something about Tati that rubs me the wrong way. She is a 37 year old woman crying about a teenage boy. She paid and flew him out when he was only 17 to do her makeup and she was in a position of power as she had a career and followers and James was relatively unknown then. If the genders where reversed and it was a man flying out a teen girl and promising big brand deals and lots of money it would be creepy. I can believe that James has made mistakes and preyed on straight men as that is what the evidence shows but Tati still did some questionable things, no matter how nice her intentions where.
Mentors can go above and beyond to help their mentees. I've known some business women and men pay the law school fees, pay their tuition fees, pay for their horse riding lessons for their mentors to excel. So it's not really weird or creepy if you have ever been in the position. Some people actually want to help.
Tati husband was the one probably negotiating the contracts etc since he had the knowledge.
I think Tati holding off was kinda questionable, however I can see the Gabriel video was the last straw because he was rude and acting like he knew the "tea".
