<human>: Could you distill the essence of the text into 1-3 sentences?

First of all, I apologize for how freshman high school this sounds. I never thought I'd be 25 and posting this. Secondly, I have two weeks in at work, so I'm not looking to date a coworker and make things awkward at work. 

My colleague (Beth) started working at my company about 3 weeks ago, shortly after I put in my notice to leave. I was immediately drawn to how unbelievably attractive I find her. We went out for drinks her second night working with us (company event) and we talked most of the night, just us two. Very fun, lively conversation. So many shared interests. I couldn't get her out of my head afterward, but the next week at work she barely acknowledged me past general pleasantries. 

Last week we had another company outing. Once again, we kind of separated from the pack and talked all night. Towards the end of the night, she was touching my arm often, laughing at my stupid jokes, gave me a few compliments out of the blue, and told me a few times she wanted to take me out to some places I had never been. I couldn't tell if these offers were sincere or not, though. 

Cue next day at work, again she barely acknowledges me past normal work conversation. I suspect she has zero interest in me, but I've never had a woman so thoroughly engage me in conversation, constantly touch me throughout it, suggest we make plans to do something, and then act so neutral the next day. I'd like to ask her out, but the reality of it is that she's beyond out of my league. Set me straight - am I over thinking someone just being nice in conversation?
<bot>: coworker is very hot and luke-warm towards me, can't tell if she's just being friendly or if she's interested.
