I have been interested in a guy that I work with for about 6 months now. We talk a fair amount outside of work and we joke around a lot. We flirt enough that most of our coworkers in our office have asked or betted on when we will finally go on a date. It also has been pointed out to me by some mutual work friends that this guy gets very 'upset' if he thinks another coworker is flirting with me, and he always tries to take care of me and will drop everything he is doing if I need help with anything. We both are kinda shy, and I've been too scared to make a move. However, last weekend, he drunk dials me, and we end up talking for an hour and we have been talking a lot more since then. Is the drunk dial a good sign he is interested in me?
