How to start?

I’ve been talking to this guy for a month, and I’ve pretty much liked him from the start, but I’ve never said anything because I thought I should take my time or even just stay friends with him since he lives so far away. But I think I’m going to tell him how I feel on Valentine’s Day (how cliché I know). But I don’t know if I’ll actually have the guts to do it🤷🏻‍♀️

I think I’d understand if he doesn’t like me back or doesn’t think of me that way. But I want him to know my feelings at least, and maybe he’ll grow to like me... it’d be so hard if we started dating though. We’re states apart...

I don’t even know how to go into a relationship. I’ve never had a serious one before. I’ve hardly ever talked to a guy I liked! How do you flirt? Is it alright to flirt? Or will it just make things awkward? I want to get closer to him...
