I developed this feeling. I dont know. Give opinion.

I regularly excercise in some nice fitness. I was also taking sauna there, this winter. So I noticed this hot, ex model, television person milf in sauna. I just always said hello to her and thats it. I have girlfriend and that. We were also in sauna few times together. I didnt ever try to hit on her as I am very relaxed and quiet in sauna and when in fitness I am usually totaly focused on my training. She must be around 35-40 years old now. She is still superhot chick and working in politics now and I am 26. But for the last 3 times I saw her in fitness she gave me this look. You know. She looked me and rolled with her eyes. And she also started to tease me and do some conversation with me. She is very nice. Very positive woman. And the other day she quite her workout quite fast and and said to me she is exhausted. She said: "have fun" and gave me this look. I mean. Do I feel hot blood in my body just because she is really hot or is she a little bit into me? As I heard she has a baby boy but I dont know if she is still married. I know she dated some rich local business man. He owns a lot of real estate and companys. I mean she could have dated politicians, actors, anyone. Maybe she is tired of all those man going after her. Maybe she likes me because I train so hard. I dont know. What do you think? Is it possible ? Or am I just too optimistic.
