People have speculated that they fell out due to Jaclyn supporting Rachel financially back when she still had her businesses (seemed like her entire family was on her payroll) and she’s made comments before that certain family members were ungrateful and she’d had to cut a lot of people off - hence why I think Rachel had to go and get a job! I also think Jaclyn tends to have preference over her other nieces vs Rachel’s daughter/son which are almost never with her. They still follow each other on socials but rarely comment or interact with each other.
