I Have A Crush On My Gynecologist

I have some kind of crush on my gynecologist, I am 31 and he is 49 and I love the way he is.
Everytime I am on examination he is very caring and gentle and doesn't feel anything weird at all he makes me feel so comfortable during my pelvic exam.He is my doctor for one year and I wouldn't change him for anyone.
He is a widower,his wife died couple years ago but he has a girlfriend now so he is not available.
I think I feel kinda vulnerable because I broke up with my boyfriend 5 months ago and I am still single, I haven't found a man to like that much to be in  a relationship.
Oh, I forgot to say that I sometimes noticed that he likes examining me more than other pacients, we had some chats about our work because I am a medical nurse so we work in the same field, we have common interests.
I know it's kinda silly to think there could be something between us but I am really shy too and I can't expose my feelings, he doesn't know that I like him as a man.
Sometimes I think of him all day and dream him that we are together, cuddling in his arms and kiss, it feels kinda nice that he is mine.
I really don't know how he would react if he knew I am in love with him.
