Opinions?

Okay so I’ve had an acquaintance that’s a guy(I’m a girl) for like 10ish years.. we hung out with the same friend group when we were younger and we hang out more now but we have never hung out alone and he has never shown any interest in me but I fantasize about him😂 so my question is would it be weird for me to ask him if he’s ever thought of me like that? Or how to start a conversation with him? Or even tell him that I think about him? Is that coming on too strong? Idk I don’t want him to think I’m weird😅
