Search Results: ask her to prom

This girl and I at work are always flirting around each other and have great chemistry. She is so much more prettier than my girlfriend. I’ve been with my girlfriend for 11 months. I am going to prom next month and asked my girlfriend out. The girl at work is 21 and I’m 19. The cut off age for prom at my school is 20 so I couldn’t invite her anyways as my date. (She went to my school and graduated in 2017 so they know she’s 21). My mom doesn’t really like the girl at work because she is mouthy. We have a lot in common too. When we walk by each other or stand next to each other I feel something like a spark. However the girl from work is being weird. she's been angry towards everyone lately. She has been keeping her distance from me and hasn’t looked me in the eye once these last two days. We have never hung outside of work. She usually stays and helps me put stuff away and we walk out together but she has been leaving 20 minutes prior to clock out time and there’s a bunch of stuff needs put away. I bumped into her and said sorry and she gave me a dirty look and said your gonna be and walked away real quick. Did she find out I have a girlfriend by social media? She also keeps moving away from me when I walk near her. What gives. What do I do? I’ve never told anyone at work I have a girlfriend and she’s the only person I really talk too at work and I’ve never told her either.
