Rejection or over analyzing?

There is this doctor that I like and who I work with from time as I give him orders for him to protocol. I have it on good info that he likes me too. His face usually lights up when he sees me and he has a big smile. I knew he was divorced with a son and his ex is crazy trying to get his money. Anyways, just yesterday I went to his office to have him sign off on an order. We ended talking for a good while about his situation with his ex and him working two jobs. He was smiling most of the time and maintaining eye contact. I told him he had a boyish smile. He said thank you. I went on to say I think it it is cute and he kind of blushed and turned around and said have a good weekend. I told him the same and left. I wondering if I should take it as rejection or did I inadvertently embarrass him. I thinking I should have just the compliment short. Did I blow it? I am a 38 yr old black woman and he is a 41 yr old British white male.
