I just started work at a after school club and there is this girl I really like. I've been working there for about a month and I feel like she is giving me vibes that she is attracted to me. She is constantly staring at me (I know because I am also constantly looking at her), she always smiles at me. I work before her in the day and she always finds where I am to say hi to me. She always laughs at my jokes (I act like kind of a goof sometimes) and the thing is that I only work there 3 days of the week and before she leaves work she asks me when the next time I am working everytime. We jokingly make fun of each other alot and she asked me to go to her dinner with her friends (whom I do not know). I would of went but it happened to be my brother's birthday. I know maybe all signs point to yes, and I am a very confident person except that I lack confidence with girls I like. So I am unsure what to do and to showing some affection because I dont want to be wrong because I work her and dont want things to get "weird" if it goes bad. Can anyone help me out? I really do like this girl and I've seriously only liked very few girls in my lifetime, so I dont want this one to get away.
