OP, if I understood your post well you mentioned at one point that the guy you are interested in is a doctor - am I correct? If this is the case: doctors usually have very busy schedules, and it could be the case that he seems 'distant' from you just because he is really busy with a demanding job. This is no excuse for not having proper communication, but it is something to keep in mind when you do sit down with him and have a talk - it's highly encouraged that you do. I wish you good luck!
