Who should I confess to?

Hi! I have a hard time figuring out who I want in my life as a partner. Please help me!

Firstly it’s between two people, a girl and a guy. I have strong sexual attraction to the guy, but as to the girl, I have only romantic. Of course I don’t feel like ******* the guy all the time, I have the romantic feelings for him as well!

Guy part:
Okay, here’s the problem, my best friend kinda has a crush on him.. buut she told me that she won’t confess, cuz she’s too shy, and besides we’re gonna chance schools anyways. And I’ve kinda liked him for soon to be 3 years. But I’ve always been too shy to ask him out. But lately I’ve felt more confident and comfortable talking with him. We have pretty good chemistry so I think we’ll get along pretty well! I do have a feeling that he’s sorta into me, so that’s great if I do decide to get with him! He never gets angry and he’s very funny and intelligent. Another thing I’ve noticed is how much of a gentleman he is! For instance he pulls out my chair if we sit next to each other, and he’s very gentle. His voice is just on point, I almost told him that he should start an ASMR channel! (Glad I didn’t tell him lmao)

Girl part:
I’ve only just recently found out that I have a crush on her, so I’ve been having a bit of a crisis (even though I’ve already come into terms with my sexuality!) I told my friend about this crush and they said that they think she’s straight, and that she’s just a bit “touchy” as a person. That made me rethink somethings and I do believe that she’s really not interested in me in that way. Sadly. But I really want to test the waters! We have pretty good chemistry, she laughs at my terrible jokes and we smile constantly when together. I have a slight, like a a very little feeling that she’s into me, not much, but a little bit. She can be a bit moody sometimes, only if people annoy her too much though! She’s quite easy going and sorta childish (I have no issues with people who are childish, as I find it pretty funny) One slight problem though, she’s going to a school far away so it’s gonna be hard to maintain contact, while the guy is going to a school near mine!

Sorry if I’m being unclear or a bit over the place, I’m just super confused atm…
