Girl Advice Needed Please

There is a lady that I have known for only about two months by now, but have only talked with her in fleeting passings on campus / via the online course chat. She seems to know that I am not a threat / not a creep, but maybe is picking up weird vibes from me because I have been nervous the few times I have talked / texted with her on strictly non-flirtatious bases. I am on the Autism spectrum, so just TEXTING a lady is more overwhelming for me than for neurotypical people, so I don't know what I am supposed to do about my current situation with the lady given that she clearly does not HATE me but I have insufficient evidence as to how she DOES feel about me. I do not know how people make friends or start relationships of ANY sort, but ESPECIALLY not romantical interactions. Shoot, I do not even know how to tell if this lady catching my eye is straight or not! I have often read papers breaking down what dating is for autistic people like me, so I can understand there are certain "games " involved with it, but I do not know how to read her signals / interpret facial expressions / text her to ask her out for coffee on campus / figure out what EXACT path to take just to get past the current rut I am stuck in. I also am PETRIFIED of my social awkwardness likely causing me to scare women off, and have been misunderstood on FAR too many occasions when the truth is I am too blunt and honest to play these dating games that other people can do so easily. I cannot PRACTICE these skills either unless I learn how to build up the confidence just to take the initial risks of communication with this lady without making her feel offended by me and my Asperger's. I especially fear the police getting involved if I ever were to accidentally say / do something to scare her that she misunderstood, for her sake as well as mine. She seems like a genuinely interesting person that I hope to talk with and get to know more about what makes her unique, but I cannot work to earn her friendship (and maybe even a possible relationship) without knowing what the first few basic steps are that I need to take now that she and I have exchanged formal pleasantries and are in a class that has met for some in-person sessions where I have interacted with her as well. Basically, I know for CERTAIN that she does not hate me enough yet to blindly reject a potential invitation out for coffee/ etc of the sort, but what next steps SHOULD I be taking so that she does not sour of me immediately? How do I interpret her responses if she is writing in 'code's and does not say what she really thinks / feels? Is it humanly POSSIBLE that I have a reasonable path forward from where I am now, at least unless she clearly rejects my legal advances? Please comment honestly but kindly (trigger warning) and have a good day everybody.
