I think I might love him

So I’ve had this crush in a guy for a few months now (let’s call him F) and he recently went to Scotland for 2 weeks (1 week left!). He wasn’t allowed to bring his phone or any technology. And I didn’t think I’d miss him that much cause it’s only a crush.... but holy shit I miss him bad... I would do anything to just see him even if he couldn’t see me. I think I might love him. I honestly can’t wait till next Monday when I can see him again. He gets back late Sunday. And I don’t know if he likes me or not, and I don’t know if I should say my feelings to him or not? Any advice would be great. Xx
