Because she can't. She's insanely jealous of Stacey and can't bear the fact that another person is doing better than her.It’s just so massively big headed and delusional that Soph thinks she can take on Stacey with this falling out and not lose out.
We all know she was playing a game being friends with SS to boost her profile (probably from both sides, but SS had less to gain from befriending Hinch given how much more famous she is than her).
Now that she’s obviously no longer mates with her cos Stace has ‘done Hinch dirty’ & brought out her own home range etc., why doesn’t Hinch just continue the friendship , however fake it is, and put on a false smile and throw a couple ‘well done bestie’ comments on Staces instagram?
Being bestie boo boos with a celeb like SS was a big boost for Hinch. “Trusting the wrong people” and falling out with her is a big loss for her.
She's a jealous poisonous old witch.
