How to attract single mom?

I like this single mom. She knows I like her as I have told her. She used to invite me for walks during lunch time at work. She lets me touch her playfully during the walk. Recently I asked her out for dinner. She refused without saying no and said she might surprise me one day. I felt dissapointed & felt I was wasting my time and tried avoiding her. But when she realise I was trying to avoid her she tries to keep in touch by calling me out for lunch & go for a during working hours. I am confused and not sure what are her intentions. I sense she still want to keep in touch even though I am trying to distance myself. I still like her and would like to bring her out for dinner & have a good time. But i don't' want to waste my time if she don't have the same feeling. What should I do? Continue to avoid her or work harder to get her out for dinner & yes have sex. What can I do to make her come out with me?
