Hubby is being a bit pushy, which is rude, but it's him taking the initiative to open up and be intimate with her, which I'd say is a good thing for him and an inconvenience that she's fine with. Good thing she was interrupted so she has time to actually think about it now though.
The prince is being a bit pushy, and he has no business doing that so fuck him. His girlfriend can totes be a friend though, and at least his interruption was convenient for the actual couple.
Worst interruption this chapter was tea tasting by far.
