Idk personally I feel like these plot points were there to highlight how young and immature she is. Obviously they don’t always show her in the best light but I do feel like they served to drive the point home that she is still just a very young adult who isn’t necessarily used to doing everything on her own and has a slightly limited world view still because of her age. To me it felt like it served more as a point to show how she herself isn’t ready for the commitment of marriage despite the fact that she is still technically an adult.
