So i work an afternoon job once a week with this guy i really like. Im 16 and he is 18 and we are good friends. we are always joking around and have lots of fun at work. He has asked me to go to the gym with him after work but i couldn't go. His friend is dating my friend and has said that i'm a cool girl but if anything happened it might be weird because we work together. what does this mean? Am i overthinking and this is just a friends/ work thing? I need opinions.
