I have a massive crush on my best friend, but she believes she is AroAce and I want to respect that

[Guest CuriousCrushes]

So me and this girl have been friends for a year, and best friends for a few months now. She is amazing, we hangout all the time, and I really enjoy her presence, even if we both just sitting and doing nothing in the same room. We have normalized physical contact in our friend ship(cuddling and hand holding etc, no sexual stuff, not do I want there to be I don't care for sexual stuff.) we have even talked about moving out together when we are older and have a bunch of big dreams for the future. But right at the beginning of us being best friends a conversation led to her admitting that she thinks she is AroAce. Which is great, I want to respect that if that is who she is. But I can't deny I feel the most feelings for her out of anyone ever. Granted I don't have a lot of experience dating. But like I'm almost crying right now thinking that this can't ever happen. And I want to know how to eventually approach this with her, or how to get my brain to except that we may just be friends forever(which is great friends are great but in the moment of my huge crush it's harder yk?) Or maybe we could be in a QPR idk. But I'm just really scared to bring it up cause I don't want to ruin the friendship. How would any aroaces like to be approached about this stuff by someone interested in them? How has it worked out? Have any of you dated and ended up in a long term relationship or even maybe marriage? Idk, any insights are appreciated
