I need advice

Hey everyone. I'm kinda new to the whole reddit thing but my buddy told me I should find a subreddit for my issue and ask for advice. So I have this friend of mine who is Asexual and Aromantic. We went to highschool together in 9th and 10th grade then she moved. That was back in 2010. We reconnected about 3 years ago and have become really great friends in the process. Now I had a small crush on her back in highschool but once she left it kinda faded. But since we reconnected it's like those feelings have slowly came back but more intense. She is one of my closest friends now and recently she finally moved back close enough so I can visit more often. Which has been awesome. But at the beginning of the year she told me she was Asexual and Aromantic. Now granted she doesn't know I have been developing feelings again. She knew I had a crush back in highschool but that's about it. A few weeks ago we touched on the topic but I didn't get into really any details about my current feelings. Just "I might be developing a crush like in highschool but I'm trying to figure it out" my thing is for me it's turning into more than a simple crush. Alot more but I whole heartly respect her and kinda don't want to bring the stuff up again but it's killing me. Granted I've been trying the whole dating scene for awhile now and nothing has really worked it's not like I'm not trying to get a gf with someone else it's just I'm having no luck right now at least. Plus my mind always goes back to her. I've been debating of taking a step back from the friendship to lose some feelings but I don't want to potentially cause damage to it. I know since she identifies as asexual and Aromantic so she doesn't have a attraction to sex or any kind of romantic relationship. I really don't want to talk with her about this and make things awkward . What in the world do I do? Like genuine advice.
