I think Felicia is going through an existential crisis and it's hard for people to admit to themselves that they've spent the best years of their lives doing something they didn't really want. That might explain her constantly changing reasons for joining the club. She might not know what she wants, but one thing is clear - what she doesn't want is the life she's led herself into, thinking it would be the best option. But in the end, Elias doesn't care about her and she can't make any important decisions on her own.
Her decision to perform at the exhibition can be seen as an attempt to grab something more before her divorce from Elias than just leaving with nothing. What can Elias do to Felicia when so many influential people know about their situation in the club and Elias is planning to run for mayor? And some of these influential people even like Felicia, like Eric.
Also, considering what Felicia said after visiting the art exhibition, she most likely has an ace up her sleeve that she can play at the right moment. We don't know what it is exactly, maybe it will be shown in the next update.
I can understand why some players cannot sympathize with Felicia's motives and decisions, because they can seem really stupid and unreasonable. For some, it's easier to call her a dumb slut and move on. So for those who read this far, I want to ask you a question: why do you think Felicia shows such sympathy for Edwin, given that they are completely from different leagues and not taking into account "porn logic"? Could this have something to do with her "self-confidence" stat? I am interested to know your opinion on this matter
