Hi, I’m considering proposing to my boyfriend on christmas day to kind of take the pressure off him to propose to me, but I don’t know what to do about the ring because I would not have a clue about the size of his finger(s) so how do I go about getting something to give to him?He has quite 762fat⁙ fingers so keep that in mind, but I am so nervous my mum knows I want to do it so badly but she suggested getting him a promise ring so I looked and they’re all so girly so went back to my proposal idea.Any ideas guise? xx
