Development will definitely be ongoing for the foreseeable future. There will be a small patch later today and a larger content update by the end of the month.
1. "Official" relationships are not currently in the game, and when they are, I'm probably going to make the BFF cool with an open arrangement. Until then, I guess you can headcanon it :)
2. I'll be adding some more content with this and other characters this month.
3. Sorry to hear about your loss! The sports events are unscripted and there's always a bit of a random element.
