First of all, fighters decline fights ALL THE TIME, you only hear about it a small % of the time, either when it leaks or when it's in UFC's interest to talk about it to push a narrative (DJ/TJ) like the sleazy, hucksterish conmen they are.
Secondly, she isnt getting shit because unlike Connie McDucker she isn't holding a title belt hostage and running from contenders. Paige is basically a joke as a fighter, only getting this big platform because she's hot, so nobody cares if she turns someone down because she's never going to be a big deal regardless.
