i f20 dont want to meet my edate m21, advice on how to tell him?

me f20 made friends online with this m21 guy, we ve been friends and we kind of e date for the past year, we watch series together and play games all day and voice chat with each other.

my fav band will be doing a tour in his country and i showed it to him and he suggested i visitted him ( its a 2 hour flight )

im usually very romantic and flirty with him through text and voice but i feel nervous about flying out and meeting and i think i want to keep it just online
