I became really good friends with a girl at my work (we been friends now for a few years outside of work) and I know all about her history and her about mine. I'm fine with it. I do find her to be attractive, she's real fit but the thought has never crossed my mind for several reasons. Anyway, the last month our conversations have been strange. One day she'll be talkin about some other dude she been talkin to or going on a date with and I'm always like

because like I said I do my own thing but then we'll have other convos and out of nowhere she'll reference how good I look and make like sexual comments (this wasn't happening at all throughout our friendship until now).
What's this about?
