So I like this guy that I have known since kindergarten, we have always been really good friends! I recently broke up with a guy that I have been dating for four years, and surprisingly I am starting to get over him, and now am liking this guy that has been my best friend for quite a while! I also work with him, so one day at work one of my co workers asked him if he would ever date me and he said I would definitely be a girl that he would date but that it could be weird because I'm like his sister! I wanna tell him how I feel about him but I don't want to ruin our friendship and I don't want to scare him off! What should I do or say to him?
