Advice Needed!

So basically last year I went to prom with an amazing friend of mine who I sorta had a crush on. He kissed me and it was an amazing night. But we had to move on cause I was with his friend before and he's a sophomore and I'm a senior. But now we hang out every Sunday and he is handsy with me and flirty and everything. He's kissed me a couple of times but it hasn't become anything. 
What should I do?? I literally don't know who I can tell about this who can help me 😩😩
