I have this co-worker she has a boyfriend, we talk occassionaly, we have had lunch once, shes told me I'm nice on numerous occasionsion, she always touches my shoulder and my arm, we were talking today about work and out of nowhere she pinches my cheek, I say "what did i have something on my face?" and she looks at me and tells me "no, all I did was this" and she pinches me on the cheek again. Does she like me? What should my next move be.
