I know "in universe" it has been a five year long relationship so it's reasonable that she is very concerned about the MCs future prospects, stability and all those things we have to deal with as adults.
But for us, players, who are just meeting her it's a horrible turn off.
On one hand we have all these pretty girls who can't wait to get in bed with you, on the other there's this girl who can't enjoy sex, and is having second thoughts, because you lost your job... we all know which side is winning.
Then comes her slutty sister and makes a dubious suggestion, i'm already thinking "how can i ditch her to focus on these new chicks" and she makes a proposal that at first view sounds NTRish (if people in this thread are correct the purpose of that was to make her a cuckqueen, but when i first heard it in game, it sounded like she wants to fuck other dudes) so everything is playing against her.
