It isn't easy to be a good wife to an internet personality, especially someone like Nick. I believe Kayla is trying her best to be a good "internet celebrity" wife by being supportive in ways that seem reasonable to her. All internet personalities share the same lifeblood: content. Kayla seems to recognize this, at least to some degree.
Kayla likely thought that taking Nick to Hedonism II, Nick's big gay birthday, and glow party would be good content in the same way that she imagined her massage "incident" story would be good content. Sort of like how one would think telling their friends how wasted they were night after night would impress them rather than seem like a cry for help. The level of immaturity present in Nick and Kayla is worrying considering their age. It seems they either disregard or haven't achieved meaningful life experiences since their late teens/early twenties.
While the content was there, they all turned out to be hurtful rather than helpful for Nick (although the farms had a good harvest). One can only imagine how this must make Kayla feel in the event she achieves this level of self-awareness.
Ultimately, Kayla is not helpful to Nick's online persona because Kayla is not a good representative of Nick's audience (outside of Locals chat) and therefore not a good sounding board for content. At least, not until she can distinguish between what will hurt/help Nick.
