I'm 16 he's 18, we met online like year and half ago online. (We never met in person or called just texting and some random pictures selfies) At the time I just thought I found good friend to play silly kids game with. At the time he was with his gf who I'll call "S". The vibes I gave him back then is like a wingwoman. He helped him prepare surprises small gifts smth romantic when S visits him. Since then he started to joke around calling me his little sister. I'm an only child and always wanted older siblings thought nothing of it for 8 months or so.

Now idk anymore, idk what I feel. I can't talk to my friends about it since I'm bad talker irl and I fear my online friends will tell him. (Don't get me wrong I adore my friends and I hope my overthinking is incorrect)

He does not know I kinda started having feelings for him. But I'm kinda tired of keeping up the act of me being just his little sister figure. He's busy lately with college and moving basically across the country so I don't want to be any bother with my stupid feelings that I don't even understand myself

(Any advice or tough love will be appreciated. Thx for reading my stupid rambling :)
