<human>: Condense the text into a few key points

We work together and were getting along really well so I asked her out to eat and see a movie on the weekend which went really well. At the end of the day/date when we were sitting in her car she said she had a really good time and i panicked and left without doing or saying anything apart from see you at work on Monday.

 After i got home i messaged her on fb (which i now realize was a huge mistake) to say i had a good time and wanted to talk to her face to face about something (which ofc just sounded weird). However now we barely talk at work and it is kinda awkward even though it seemed she liked me as more than a friend before. Have i fucked this up or can anyone give me any advice?
<bot>: Went on a date went well chickened out of any sort of romance at the end to instead send a weird and worrying fb message to her.
