So, why did Robyn ultimately decide that she didn't want to go back to the house with Simon? And what was the look for that she gave him when she was holding the baby?
I mean, for all she knows, that is his baby too. It's not like she knew what happened when she was passed out, so why would she shut him out like that? I feel like that escalated quickly.

good points
shareBecause she can't trust Simon at all.
Gordo is part of it... but the final nail in the coffin is the Danny McDonald incident.
She finds the files about Danny and Gordo and when she confronts Simon about them, he gives her some half truths. He doesn't stop there though, he then tries to blame everything on her and her own past and mistakes (the fact that she was bullied, and the fact that she used drugs).
She sticks with Simon because he promises to visit Gordo and apologize, and because he feigns remorse and plays it off like he did something shady... but nothing outright evil/illegal.
Simon then sees Gordo, and upon return and says he's apologized and that Gordo took it well, which again, was a lie.
At the dinner party, the truth about what Simon did to Danny McDonald (and the depth that Simon took it) is revealed and all the pieces finally come together for Robyn and she sees Simon for who he truly is.
As far as the last look, I think it's one last "eff you, you're never coming anywhere near this kid" because of her final interaction with Gordo, where he approaches her all beat up and she figures out it was Simon who did it.

I do have to say... I think that Robyn's 0 to 60 reaction is one of the more unrealistic aspects of this movie (not that there aren't many others). I think the director was trying to wrap the movie up though, and skipped a bunch of stuff that could have been inserted to make Robyn's decision look much more rational and much less Hollywood.
