Waiting to inhale - what's happening to the plot of The Woman Upstairs?

Reading along and waiting for something to happen in Claire Messud's The Woman Upstairs. Let's see, she's in her studio at night and the husband of her studio-mate, friend, and mother of student stops by - he's obviously been there before at times when Nora was not around and this disturbs her for some reason - and he kind of flirts with her and she's obviously attracted - she says he's her type - and then she has a sexual dream about him that night. Okay, but will anything develop here? We're 100 pages into this 300-page novel! Meanwhile, a 2nd bullying incident - and Reza, the son of her studio-mate, gets cut by a thrown rock and Nora is stands by them, spends hours at the hospital, etc. She really has a crush on Reza's mother, whether she knows it or not - and she does go to some lengths to include in her back story the tale of her engagement and breakup, which informs us that she's not, at least overtly, gay and that she turned her back on a corporate career to pursue her love for art - even if that didn't work out perfectly and she ends up teaching 3rd grade and doing art projects just for pleasure and expression - and what's wrong with that? Isn't that what millions of people always do and always will do? She may be great teacher but she seems resentful about every aspect of her job - and she's kind of going off the rails here, not mindful at all of the boundaries between work and life - becoming way too close to the mother of a student and in the process losing judgment. Will this have dire consequences? I hope so!
