Should I ignore this girl and avoid her?

[Anonymous]

There is a girl at work who flirts with me a lot and shows me a lot of signs of attraction. I found out recently though another co-worker that she has a boyfriend. I was puzzled because she never brought him up. I tried to pry and see if she mentions him by talking about a place she went with him but she said "I went with a friend". She is hiding him but at the same time sets boundaries where we never really talk outside of work. I dont text her, she doesn't text me.

Should I just stop talking to her?

Yeah, avoid her. She'll cause problems for you

If she has a boyfriend leave her alone.
