I'd like to add something to what @Splaterfan64 said
1. would love to see an option for the feeder personality girls to gain as well, this can very well add to the feeders leveling system as well
2. addition of random events into dates, like a kid or a grandma coming upto you and offer you maybe a cookie or add in something like going to a place with an event [with a date] and seeing another girl you recognize already participating in the event. This can help you add jealousy into the game and competition between girls
3. passive weight gain or loss for the girls depending on their personality and etc
also keep up the good work, really well made game
