Yeah, nvm figures, anyway, how to do the roommate's girlfriend quest where I have to sneak out and send her a photo? I did what she said, and I've sent her a selfie but after a week she still said that I didn't do it and then she stops interacting with me(??)
The roommate's partner wants you to be some distance away for that challenge. If you head toward the park and walk around a bit in that area, an event should automatically fire about sending them a selfie and that completes their challenge.
Even if you fail to do it, it shouldn't be the end of the storyline. They should punish you but then issue you another challenge within a week or two.
