This was fun, but parts of it were really disappointing to me. 
I kind of hate the idea of dating apps and have yet to use them (probably why I'm still single) so it was kind of funny to read about the whole friend group trying it out. I really like the first half of the book.
Tbh the oversharing on the dating app between the two was wayyy too much for people who "haven't met". It was weird more than refreshing. Of course honesty is the best policy, but like... on the app? Before sharing numbers or meeting or anything? I don't think of myself as closed off but that would make me so uncomfortable.

I hated how the ML reacted to the FL keeping a secret profile, and hated how when he comes back to her, she accepts all the blame. Like, she comes clean and he literally ghosts her, taking away the entire friend group with his awkwardness (which is clearly her only friends and support). Why would this make her want to open up more to him? I get that she shouldn't have lied, but their communication problems are so obviously not one sided. She has been putting more effort in all along. He shouldn't be punishing her and she shouldn't be ok with it. The friends like Ed are better to her than Reed and seem to understand her. (And like how did he not figure it out way sooner?)
