What should my friend do ??

Kk i need help on this , my real close friends lets call her kate met this guy lets call him aidan last semester and they sort of liked each other , but he told her that he doesnt want to be official just between the two of them , and as me n 2 others friends are really close to her , she did tell us about him and how she likes him , but one of kate's friends texted one of aidan's friends about kate likeing aidan and aidan's friend called aidan and told him about it . Aidan later called kate and informed her that how he trusted her and how she went n told her friends n didnt keep it discrete , so he called it off , do you think she should get over him ? If so how ?? Plus she said that there aint much ppl in our college she could click and pair with
