She’s attracted to the stability and the idea of that clean-cut finance guy, not necessarily the lifestyle that comes with it. It’s like, on paper, he fits the “grown woman” version of what she thinks she should want at 33, dependable, polished, financially secure. But emotionally or creatively, he might not spark her in the same way.
Plus he can fund her art ventures lol. Most of the times in these dynamics, her personality provides enough personality for the both of them. His personality shines through her because she’s expressive while he puts his head down and looks at charts.
Dating another artist would be competition (success, getting dressed, etc)
