<human>: So I've been working with this girl Amy for about 2 months now. She is a sweet girl, but she is infatuated with me even though she knows I'm with my SO. My SO Taylor also works with us. Amy has revealed a lot of personal information to us very quickly, and has told us that she doesn't have any real friends. Taylor and I talk to Amy on almost a daily basis (usually reassuring her, and listening to her vent about her insecurites). 

 Amy has revealed that she has Autism (which explains many things), and has it in her head that we three are all best friends. 
Taylor and I have no problem talking to her or even hanging out with her outside of work, but we are feeling like she's trying to move things way too fast, and is starting to push our personal boundaries. I have a feeling that if we confront her about this things may turn ugly at work, and she may do something to herself because of it. What should we do r/relationships??

Can you give me a shortened version of the text?
<bot>: Co-worker wants to be besties with my SO and I, and is moving way too fast for us. How do we deal with the situation without rejecting her bluntly, or compromising our own boundaries.
