So I do and don't agree with the argument that she is just a hoe , now il try and not make this super wordy but no promises haha
Now before I start this is purely my opinion and there's nothing in the game to support this as of yet and yes it is just a game and it boils down to what way the Dev wants it to go but I'm trying to look at it and address it in a somewhat realistic way
So let's say she is just flat out a hoe and always has been I'd be more surprised that she has kept that side of her under control for 22+ years, I would of expected that dam to burst much sooner truth be told , now one way it could be done and I'm going to reference another game for this - so the game is my bimbo dream and let's just say she had a very adventurous past/younger days until there was a traumatic event which caused those impulses to disappear essentially like turning off a light switch but for this we would need more of a backstory around her past as without it I don't see it working
Now I agree that her "hoe" antlers just didn't grow over night, but with this it doesn't necessarily mean that she's a hoe , i would say it's not uncommon that in long term relationships that people's tastes change or want to try new things , probably the most common trope with this is the "I've been a good girl all my life " logic and they want to rebel and be adventurous
Now with this all starting I do genuinely believe that she thinks she's doing it for the right reasons and doesn't see it becoming a regular thing , but I would say as the story progresses it definitely becomes that she is doing this for herself rather than hutch and that she is hiding behind the shield that it's all for hutch so that she doesn't have to admit that she is a bad wife or that she is in the wrong , so there is a massive denial element to it all on her behalf
So I would say without any supporting evidence it's a hard sell on any theory around it as there's nothing to support it ... Maybe this will come in future updates but who knows
Now this next point is definitely based around what has happened in the game and I can evidence it and I would say this could be the most likely idea or theory to it all
So it is clear to see that when there is some form of conflict that directly involves her she doesn't know how too or lacks the ability to problem solve and actual deal with an issue in a proper way
So from what I have seen Vivians go to resolution to a conflict is her body/sex , so here are my examples: hutch may or may not lose his job so that effects money into the house .... Resolution - Vivian fucks Christian , Vivian can clearly see that hutch is not himself and she believes that he is mad/upset with her... Resolution - sexy times and actually goes to the point where she offers anal but when hutch rejects this she is like a fish out of water and has no idea what to do next , in that same scene she actually references that hutch can never stay mad at her when she turns it on and offers out the sexy good times so it is clear to see there is a trend of this
So it could just be that this is what happened and before she knew it the situation got out of control and got away from her.
Curious to see what you say back to this haha
