I like a guy at work and I'm pretty sure he is in to me. We are developing a nice friendship. We do flirt from time to time. However for the past few weeks he has called me by my first name excessively when chatting. " are you okay , Emily?" "Oh hey Emily" "alright Emily" He hardly did that prior. Occasionally in a email or something , yes but hardly in person. Now it's like he is trying to wear it out. My sister said maybe it's because we are getting closer. Others say it's a sign of respect or being personal or even just plain friendly. Please tell me your thoughts?
