Wanting to Proceed

I have lived in my current building for a month. I had an instant attraction to the man who lives above me. Though I do not know too much about him, I do know he is single and unattached. I also sense something very special about him. We are constantly running into each other. . in the parking lot, stair well, laundry room It is almost unnerving.

I have sent him the 'green light'. . and he seemed receptive, but he is so terribly nervous around me. It seems to be getting worse instead of better. It has got to the point that when he says something to me it is usually an uncomprehendible mumble. Though he does always manage to give me a nice smile.

I am a confident, attractive, intelligent and sexy woman (so men tell me). How do I make this guy more comfortable with me?? I have thought about using the direct approach but our chance meetings are usually brief and his obvious nervousness deters me. Part of me would just like to say. . . forget about him. But my keen intuition and that little voice in my heart tells me to hang in there, that he is worth the wait and the chance of something good.
