Sigh last attempt, most of us are not blaming as such. Mostly wondering. Just as we are not assigning blame to Jaye alone, MC alone or parents alone. We have a disagreement about jaye's actions and reactions to MC and I tried to show you why. That does not mean my opinion is per se the valid one or the one devs will go with.
Considering Jaye sex, well between Jaye and MC makes no sense at this moment in game and I do not care for fact she had or did not have relations with Christian or Tara, beyond not liking having sex scenes shown that do not include MC in general. That is something the skip fast through function works for and if devs want it in they can.
Considering Jaye, last attempt. Most of us get she is conflicted and also hurt by MC's behavior and also angered likely more than once. We get she felt betrayed by MC by his running away and him refusing to answer her after even when she tried to apologize. That all those things from past feed into her current actions and that she did try to extend an olive branch once or twice as with the texts, requests for talk in coffeeshop and that MC basically shut that down.
Now the thing is that we also understand MC, MC is just as conflicted as Jaye. On the one hand he wants to love her and be loved by her. On the other hand whenever he is in her company he is often hurt by her, belittled by her (the name calling) or even attacked by her from his pov, however understandable those things are from Jaye's pov. Now unless you are a masochist, you do not enjoy those things done to you by someone you love, they hurt and they hurt bad.
Now it lead MC to running away for 5 years since he did not want to handle that anymore or found it fun to be around her, but painful. After he is forced back by death of their parents, remember he did not come back of his own free will cause he thought he was able to handle living with Jaye again. He gets attacked by her over blocking, being late funeral which was not his fault, called names, has her exploding on him over a kiss for starters. As positives we have the texts and her wanting to talk, well those emotionally do not outweigh those other things unfortunately.
Leading MC to remove himself to Aspen and refusing to have that talk Jaye offered. Smart from MC, no. It would have been wiser to man up and not postpone, then again MC may not be so interested in that talk and reconnecting to Jaye either, beyond the fact he loves her, but that other part is also there and Jaye was pretty effective at reawakening that pain and fear in MC after his return despite her better moments.
Now that is the thing, though Jaye's behavior is understandable and relatable from her own emotions. It is also exactly the behavior that will not make MC feel better in her company and with some introspection that should not be beyond her age to get even without the knowing that little fact they love each other which makes them even better at hurting each other and make their interactions have a bigger impact as if they were just bro/sis. It is like having a problem, choosing a way to solve it. Fail and then instead of choosing another solution, doing exactly the same, without wondering why result is failing again to solve problem and then do it again.
Just as that question, why he was not at her graduation. Now I personally took that question more to mean, why did you not give me a chance to make up after the scene of the party, but some of the snide remarks about that is cause unless she is blind the simple answer is clear as glass. MC did not want to be around her anymore and was willing to leave all he loved behind to reach that goal, so why would he have want to be at her graduation in the first place?
Now of course Jaye can just continue acting out of her emotions and if she did no one would really blame her as such, but it would also mean her goal of reestablishing a healthier relation with MC will be impossible. She does need to get some grip on the messages she sends MC and understand which ones she is sending intended or unintended as with not going game and inviting Christian to party whatever her reasons were for doing so and make those less negative with more positives mixed in. Just as MC must find a way to open up and stop making it so easy for Jaye to act from her emotions to him and understand a bit more Jaye acts out of her emotions and not per se to hurt him.
Considering the competition. Well in a situation where at least one of the two is already trying to stay away from the company of the other cause he does not like to be with her, bringing them in a situation where they are to compete together and are quite likely to hurt the other in the process, that would not have been my first idea if I were their parent .... The other things, well current state of game leaves a lot of suspicion and wonder open concerning the parents, even though I agree that though they have painted as basically loving. We will likely find out more later but way more negative explanations or speculations for the actions of the parents even if they had the best of intentions from their pov and their actions might well have not been in the best interest of Jaye and Mc even if the parents thought they were. Things like that happen. We will see.
Well this is a game and admittedly parents might have expected this to happen 20 years later and maybe had more time to train both, but at this moment I would not say either Jaye or Mc has the mental makeup or skills to lead a multi billion company when look at them from game perspective and I would def be moving my money out if I was an investor with either or both leading the company.
