Met this girl a little over a week ago at work asked her out she said yes. The next day she "nicely declined" and said she wanted to go out but wasn't feeling well. We'll the past week at work I would see her 2 maybe 3 times and the first night we hit it off everything was fine. Then a few days later I saw her again and started chatting her up. She gave me a hug at the end of night and we left on good terms. The past times I spoke to her we talked for hours like 3 hours at a time. We were getting to know each other and everything was fine. Fast forward to tonight. This morning I woke up and wanted to do something nice for her and just put a smile on her face. I bought some candy put it in her desk this morning and wrote a note on it. Around 2pm she sends me a text with a picture of the candy and some emoticons saying thank you and that she was happy. Anyways I come by around 430 cause I finished work and wanted to chat with her again this time I was kinda hoping to try and get a date. We talked for 2 hours like we have in the past but I know she has been busy with school and is kinda stressed. She was doing hw and decided to go to the break room. I hung around on my phone and was talking to other people enjoying my night. The weird thing is she came back with a sad face and kind of a stern voice and just said "you shouldn't be here after hours when u have already clocked off" I was kinda shocked and just said "ok I'll leave " as I walked Away I didn't look back and she said "have a good night" and I just said u too. My curiosity is why the sudden mood change also was I bothering her that much? I only saw her once every 3 days and I just wanted to talk with her but should I take it as she isn't interested and move on or should I leave her be for like a week and let her focus on school.
