I am a 23 year old male with social anxiety and have always struggled with dating and often have crushes on people fast at times. A few years ago, there was this girl who joined into a Discord server of mine for a hobby I have. The girl is a seemingly nice person although seems a bit shy as she doesn't talk too much but when she does it's usually very descriptive and I often find it interesting to hear what she has to say even if it's about something I don't know. We seemed to have become friends and as time progressed she seemed to talk more often and we learned about each other a bit more in the server.

At first I kinda started to have an infatuation mainly because she was a girl and such but that sorta died out quick as I briefly dated another person early last year but we broke up as she lived in another country, language barrier, and also for other reasons but we're still friends. Well a while after I stopped dating the second girl, my infatuation kinda sparked again for the first person and I constantly think about her and try to be online around when she is just to chat or respond to her. We followed each other on other social medias as well in recent months too. Although, we never talk much privately unless we have to say something more privately, I kinda wish to be able to speak to her more in private to know her more but I don't want to feel like I'm bothering her or anything as I had some bad experiences related to that before. Also recently at one point she had mentioned she never dated before due to nobody ever talking to her and asking her to date and I don't want to overwhelm her or make it seem like I want to talk to her just because she said that. I have dated before in person once and talked to a few girls online that unfortunately didn't lead much of anywhere so in a way I still feel crappy at dating and talking to girls due to social anxiety and being shy. I never had a serious girlfriend before. I should also mention I am on the autism spectrum but on the high end of it so that brings other little issues.

What should I do? Should I move on from the crush? or what should I possibly say to her so maybe we could possibly talk more to each other privately without messing things up? I fear she would possibly say no to me or something as what had happened before when I asked people out. She is also about 3 years older than me so I feel that maybe that's another problem for her? though it isn't for me, and we live in different states.
