Is she trying to tell me she wants to be more then friends or not?

She has stopped by to see me three times in two weeks. She has to go out of her a way a little to see me too, she told me she was going to come visit everytime before she did, i didnt ask her to. Its not like she didnt have things to do, she had three kids waiting for her at home too. While she is there sometimes she will fix her hair or will say its a mess. I had only known her a week when she started coming to vist. One time i asked what perfume she was wearing and she actually came over to me and left me smell it. We flirt some but mainly we talk about serious things that are happening in our lives and i noticed she seems to smile as soon as she sees me. We seems to be always laughing and i noticed she is always attentive and making eye contact when we are talking. Are these things a woman does if she just wants to be friends or is she interested in more.
