What it all boils down to is both are at fault in some manner. Not sorry Cinders Simps but it's the truth.
Wades certainly at fault for not nuturing the relationship that he's somewhat taken for granted, thats true. And sure, his gaming passion has taken hold of him with him as of his rewrite (when prior he did have a job) and chapter he might just be getting his chance to possibly signing with a team. Same time though, he's begrudingly put in efforts here and there for Cinders at times, though if we are that true friend and are trying to help them out we do see him trying to put in more effort, even though Cinders passion is coming into conflict with it.
Cinders is also at fault for a number of things. Willing to keep her passion a secret, even though she outs herself by posting her modeling pics if we keep quiet about it or don't talk Wade into putting in the effort. Doesn't take no or rejection well and acts out in a bratty behavior if you make a retort or don't support her choices. Condecending to Lena singing when Lena potentially talked to her about the modeling business. In short: A bratty, need to be pampered 24/7 girl who expects undying support for her choices or passions or else she acts out.
Sure, there is nothing wrong with her wanting to be pampered a bit, and yes Wade is a fault for not doing such more than he should, BUT she expects things to go her way all the time. Like Geralt mentioned, don't go to Wade's Party in favor of Holly, she's pissed and upset because she didn't get her way. Well BITCH, your not gonna get everything you want. Grow up!
Honestly though, as much friction as they have with each other, with both having their passions starting to pay off (Cinders getting the modelling gig/Wade potentially signing with a team), my BIGGEST hope is that they do eventually work it out, considering I'm trying to help them both out. It would be a damn shame if I've put in all the effort, went through all the loops and holes just to find out Cinders and Axel are banging even though I've tried to help them out. Knowing Eva... probably 60/40 on that.
I do fully think they could work it out, but they both really need to compromise with each other big time, and talk more. Wade needs to hit the gym, and if he does get signed, take Cinders on a date: nice dinner and movie, maybe a bit of the club scene, then treat her right. Cinders for sure needs to understand that she can't have everything go her own way. She needs be willing to compromise things without acting like a brat. She also needs to be more upfront with her feelings and passions rather than keep quiet and keep it a secret.
