Should I ask this girl on fb who were not friends but found her fb & message where about of my crush?

This girl who I used to work with pretty sure had a crush on me she would flirt with me, check my behind out my telling me I dropped something when I would bend over, asked me if I had a gf, etc.
I don't know her last name and she said she worked at k-mart but I don't know which k-mart she works at and this other co-worker might be the only one who would know her last name.
