Is she the one for me? ?

I met this girl at a ball game three weeks ago. She was attending to watch her brother. I got to talk with her and we exchanged our e-mails. We went out to a coffee bar one week later and she has visited me two times. I wonder if I might be too old for her. She is 23 and I am 42. I think about her all of the time and she is so beautiful (with long, chocolate colored hair and greenish blue eyes. She is around 59 inches). We have only had friendly conversations but I like this girl. We have talked about our jobs, music, food, politics etc and we have shared some jokes together too. She told me that she is abstaining from until marriage and she is a devout baptist. I respect this girl very much for her self respect and her wish to wait until marriage. I am divorced with 2 teenagers and I work as an economist. I really want to marry again if I find the right one. It feels that she is the right one for me and I think about her everytime before I sleep. She said she would come and visit me the next week. I am longing to touch her, kiss her lips, caress her...... She hasn't showed me any sign that she might like me. Should I just kiss her and hope for the best? If she doesn't like me, can I lose her forever? I don't want me to think of her as a pervert but she told me she liked mature, respectful men. Should I do everything to make it romantic for her the next time she arrives? Or should I just forget about it? Am I too old to have a chance with her? Is this girl just looking for a friend and nothing more?
