Your fan character/s are walking in the park, and u see Beanie looking at a ring box looking rather nervous. What do he/she/they do?

He's planning to propose to his girlfriend Cleo, but he's nervous that she'll refuse, and if she says yes, that if they don't get on any more, there's no going back because he doesn't like divorces. What should he do, of how does your fc help him out?
