Two months ago I got in contact with celebrity (around 6 mil followers on instagram), the singer in question was really responsive to my messages and we were messing around via texts (not regularly, every few days or so) and seemed like a nice guy, few days ago I told him we should meet and he actually accepted my invite.

We met, (my gf also stopped by) and ended up being together in a nice bar long pass the closing time(around 4 AM, normally closes at 11 PM) because the owner also joined and we all actually had a really great time.

The bill was around 80 euros, I wanted to pay and handed the money to the bartender, but the person of interest insisted he should pay and he did.

That was a few days, we exchanged few message from then, I want to keep our relationship, he's genuinely nice guy, nothing seemed forced, he more than once said he enjoyed my company and that he'd like to take me on his gigs (backstage), after which he drove me home.

Can anyone give me some advice on how to nurture and keep relationship alive?
