Is he interested in me? Is he just doing his job or flirting?

Recently my doctor has been making some unusual comments towards me at our visits. I am divorced mother of 3 and I ended a long term relationship a few months ago when I found he was cheating. So since I really haven't been dating, just with the same person, it's hard for me to tell what's flirting and just being nice.. But I was having problems with my bp and also that my temperature was constantly elevated, I always felt hot and I tended to perspire alot. I was honestly concerned I was starting menopause early. His comment to me was " Baby, you are hot!" So it took my by surprise and I just giggled. I had no idea what to think. So then the next time we were there I took my teenage daughter because she had an upper respiratory infection. Instead of the nurse coming to the lobby to get us, he came and using our last names, said " The our last name are here!." So we went back to the exam room. During the exam, my daughter has epilepsy, I reviewed with him the meds she was on. She's sees a neurologist at a large hospital for this condition, not a primary care, of course. During the visit, we talked alot about a lot of things. How the kids were doing in school, sports, and my job as a teacher. So then he stated, "You've done a great job raising them on your own and if you ever need anything just give me a call." Not truly understanding what he was meaning I explained she was doing great and they had her seizures under control and she was doing great. He then restated it, and said "Well you know if you need some refills, can't get to the hospital just let me know if you need anything." I thanked him and we left. Then my daughter said "Well that was embarring." I asked her what she was talking about and she said the way he was flirting with me. I was shocked because I really hadn't considered it. So I started to have some problems with my bp again and just umed, I needed my meds changed. So I went for the appointment alone and this time he again came to the waiting room and called for me. I had watched and the other patients were taken back by a nurse so this was unusual. So we went to the exam room. He was very chatty again. He took my vitals. Not a nurse, which this has never happened at any doctor I've been to. So I was wearing a blazer over a silk-lace cami, I had went straight from work. So he couldn't get my bp with the blazer on, so I had to take it off. So then he said we had to go out into the hall where the scales were. I put the blazer back on and he said "Yeah that's a great idea. You walk out of this room like that and you just might cause some of these old men running around to have a heart attack." Once again I was shocked and just laughed at him. So when we came back into the exam room we started chatting again. He knew my relationship had ended because the last time I was there I had attributed my bp being elevated to the stress of the situation and it ending. Then he said, "Soooo are you back in the game yet?" I stated that I wasn't and I had been out of it so long, I didn't even know where to meet anyone. He then stated that I needed to go to the grocery store that is only in his town. I was a little confused. I teach and live in another town about a half hour away from his office. So then we finished up the appt and instead of him writing a prescription for my new meds he gave them to me and said come back in a month and I'll give you some more. I understand doctors give samples away all the time. But my blood pressure is always going to be high and I'm always going to have to be on meds for it. He has been our doctor for awhile but I do know he just divorced. So what do you think? Thanks!
