Thanks JClarke and Shel. I do like him more than friends. I haven't come out and said that, but I think it's obvious. We will exchange a few nice emails and then I won't hear from him for a week. This is really annoying. I am sure he knows that I am flirting with him and that I like him. Next time he writes me, I am going to tell him that I want to date him and ask him if he is interested.
His emails are very brief and sometimes hard for me to understand so I keep my replies pretty simple because I want him to be able to understand. I really feel like he likes me or is curious but tries to distance himself by stopping communication.
