How do I stop crushing on my primary physician?

First let me say he's a wonderful doctor. He is very caring, professional, informative and supportive. Second, I will add that he's quite gorgeous and only three years older than I. I am feeling a lot of chemistry and sometimes his support can be misleading. I pick on his vibes that he's interested and I am too, but the last appt I had with him he seemed very nervous, forgetful and kind of too clinical. I am wondering if I am making him nervous because I dress in skirts for my appts (knee length). Is his nervousness and forgetfulness a sign of interest, a sign of guilt because he likes me, or what? Thanks.
