Her desire to be rich comes from her need for everyone to think she's better than them.
She's said before she's got daddy issues
and must have some massive insecurities based on that.
When she was with Kal she felt that she had superiority over everyone else from alledgedly having a 'happy marriage' to a famous rugby player, him financing her to stay at home and look after the kids, and them being 'relationship goals' according to her blog because they'd overcome loads of obstacles together to be 'so in love.'
Now she's not got that, she still needs the worship, so now in the blink of an eye she's this top tier bad
witch 'businesswoman' making millions
if that ended she'd find something else again
