You know that what makes someone's personality interesting is different for everyone? Do we know the bigger picture of why Veronica is so stubborn about this gym, just like Felicia is about her chosen one.
Yes, we know why she is so stubborn about the gym and it is the main reason I consider her stupid. It is good to have emotional attachments and rules of conduct, but when you knowingly ruin your marriage and are drowning in debts because of the fraking gym you trained in to become a wotld class sports person, you should take a step back and seriously think about if there is another way without that gym! It gets worse in that unlike Rosi and Feli, who would gain what they want from a win, Veronica knows and tells us that even a win at PC would be nothing more than a shortlived band aid. She would continue to drown in debt once the money from PC would be gone.
And it has been mentioned several times in-game, that Veronica could simply toss the gym, take the hit and start over with another, better fitting gym including living her dream with it.
I let you decide for yourself if Veronica is stubborn, consistent and/or stupid here. My verdict is clear due to the overwhelming evidence.
Like is Elias beating her for her to chose this route if it is just his disinterest for her then it's all in her mind and she is being childish just like Veronica because just like Felicia she can control her situation with a little bit or more of compromise but no both are stubborn enough to do the worst Veronica probably because of something with her ex and Felicia because she isn't having "affection" from her "money bag", she needs to learn that "you can't have your cake and eat it too".
You either never played the Felicia route or deliberately distort the situation. Elias was dumb to not recognise the raw gem Felicia could be for him. He could have gotten everything from her and unwavering loyality into the future, had he saved or reopened Felicia´s old art school.
Flippantly speaking, while a serious investment, Elias is so rich, he could have taken the money for the school from the post stamp money without blinking and totally win over Felicia forever. Even scoring PR brownie points along the way.
BUT he did not and even taunted Felicia with her powerlessness and he could easily save the school but did not to show her who has the money. That is a bad and seriously dumb move even in a mainly business marriage.
