I literally cannot understand the marriage plot

okay, i know this show is supposed to be a super unrealistic teen drama but I still can’t understand why belly and jere are so desperate to get married?? they’ll both be done with school and a year and they’d been dating for four before the cabo scandal happened, so i don’t really get what the rush is, especially so soon after getting back together. does belly think getting married is going to magically solve the trust issues the lacie situation created? the entire of ep 5 when belly was freaking out over how they were going to pay for this wedding, i just kept thinking to myself how this issue is SO easily solvable. like, you guys can be engaged for a year and get married when one of you is no longer $20,000 in debt. does belly not realize she’s going to inherit that debt too?? it makes it so hard to sympathize with either character. i know it was probably done to up the stakes for conrad to confess he never fell out of love with belly before it’s “too late” and she’s tied to jeremiah permanently, but i would’ve rolled my eyes less if everyone involved was a few years older. i’m the same age as the main characters and neither me nor any of my friends are even thinking about getting married rn.
