Title of chapter is my reaction. And I dont understand the Goddess creating an alt-timeline where she just moved in, that isnt remotely the same as what she told Shiho at the end of chapter 5. The Goddess was talking about Shiho calling him after the date so I'm guessing the author said "fuck it" and created a new timeline instead of having her go back in time and hopefully fighting it out with the dick of a third friend.
Goddess asked her what her wish was...she probably said that she wanted to see him again. It's like the old Jinn stories...be careful what you wish for.
She cried in the river first. Also...never heard of denial? It's clear she was still experiencing that stage of the 5 Stages of Grief. Not to mention shock...
