help with a qpr

i’m looking for advice on platonic feelings/ if a qpr is a good decision for us.

for some background i’ve known my best friend for around 5-6 years at this point? but she’s been my best friend for about 3 of those years. we recently started getting even closer and sharing more with each other than we usually would. (we’re both a little closed off) very recently we’ve talked a bit, pretty deeply about our struggles which i feel brought us closer. we both agreed that it feels different with each other, like we’re more ourselves with each other. i felt a shift recently of us just being so in our own little world sometimes. and other people comment on it as well. we also show a lot of physical affection. i have never been big on physical touch and she was even worse than me. but now we’re both so comfortable with each other with that. physically we lean on each other a lot and grab each others hand and arms and just other types of platonic touch we don’t do with our other friends. she’s my best friend and i love her but i don’t think i’m romantically in love with her. i am for sure asexual, more on a lesbian oriented aro spec? possibly demi romantic? i’m honestly not 100% sure on the aro spec part. but she has also recently been curious if shes asexual. i don’t think i have romantic feelings for her, i just love her being my best friend but it does feel like a little more in a way. (mostly because of the physical touch but also because of our emotional closeness) i just love her presence and we always have so much fun together. i don’t know if it’s appropriate to ask her how she feels about a qpr. she does know what it is luckily. but i don’t know if she’d be upset that it isn’t a romantic relationship. and i don’t even know if she’d want us to go any past friends. but at the same time i guess i wouldn’t be completely opposed to a romantic relationship with her. but i don’t feel i necessarily want a romantic relationship with her because that feels too far from our friendship in a way? but i’m very happy with how we are now too i was just thinking on our friendship.

any tips on how to ease into this with her? and how to test the waters if she would be interested in a qpr?
