I think one of my students is STALKING me?

I have one student I will admit I am more attached to her because I have known her the longest- and now I am starting to think our relationship is unhealthy. I never tell my students about my personal life (i teach karate and it is not important) but whereever I would go 5 minutes later the girl would show up. Like I work for sprint when I went to work I saw her and started communication seing if she had a relative or a friend who works there- no. (maybe kids are different today but I didn't hang around at random buisnesses) Then I go to the bar after work and she shows up there w/out a parent- I am sorry but there is NO reason for a 14 year old girl to walk into a bar- period! I took her home and I didn't see her for the rest of the night. She is not dangerous or anything- but it is rather creepy and very inapropriate, I am 56. Am I just being paranoid- how should I handle this. (i never saw her fallowing me, but it seemed to odd to be a coincidence)
