A non-expert and somebody's not chatting with me..

These days I feel weird... I seem to be wanting more time in front of the computer! And I think a part from the reasons is that I feel like chatting to him. I go straight to Facebook after I open my computer maybe because of him...! I feel like bumping into him in Facebook.. But I always dunno what to say, what to ask, how to start a chat to not make him feel...... uncomfortable, annoying and that I'm bothering him... I'm really not an expert in this!!!
