Freinds behavior has me confused?

so I met this women at work and we hit it off pretty well after we got to know each other. She's a natural flirt so she flirts with everybody. I believe she has freind zoned me which I'm mostly ok with. I just find it odd that whenever we hang out she never mentions me just says somebody. Should that be a red flag? She always says to me there's not a thing you don't know about me and I'm pretty sure that's true. She's told me everything. Is she embarrassed or something?
