That would be going back quite a while, unfortunately, and I can't quite remember when I started cheating, so I think I might just start a new save and focus on her.The thing is if you have edited your save it's probably bugged now and the event won't trigger as The Devian said it's best to ask here first
If you do have an unedited save load that and play until the point you're stuck and tell us what her hint says
FWIW, her hints are: "We really enjoy watching Netflix together." and "Let's go watch some more Netflix with her."
