I sit next to a girl in my class who has autism like me and we're into the same terminally online shit (rare from where I come from) and most of my friends know I like her but the problem is that she acts interested in talking to me but also not at the same time and I honestly don't even know if she's into boys much (she's bi) and I feel like she thinks of me as more of a friend. I was planning on getting her number by the end of this week but I honestly don't know what to do anymore.

For reference, no girls are ever into me and I literally don't talk to woman at all.
