<human>: Can you give me the gist of the text in a nutshell?

I have strong romantic feelings for my coworker. We have worked together for several months but only began talking about a month ago. She's smart, inquisitive, interesting and beautiful. I told her as much after much deliberation (I know, I know, office romance etc but we're far enough apart that it's not a factor).

She had been dropping hints etc and admitted as such but said she simply wasn't interested romantically and wished to be friends instead. At this point in time we had been taking our lunch breaks and other breaks together daily and she wished to continue to do so and get to know one another better etc in the context of friendship. 

I thanked her for her honesty, apologised for any awkwardness I may have caused and politely informed her that I was not interested in a platonic friendship. 

She was immediately offended and accused me of leading her on and being a 'nice guy' (I was genuinely confused until I looked it up, I don't follow memes etc very much). I apologised once more and took my leave. 

She is angry with me now and has text me as much several times. 

Was I wrong to do what I did? I really like her but I have friends and I don't want to be emotionally intimate etc with someone I have unrequited feelings for.
<bot>: I want to explore a romantic relationship, she wants to be friends. I said no thanks and now she's pissed. Am I a dick?
