What are signs a girl is unhappy with her bf?

Anonymous
Are there signs that a girl is not happy in her relationship? a lot of girls have boyfriends these days, but there are a lot who aren't happy either so what are signs when talking to a girl who has a boyfriend whether or not she's happy? I've been talking to this girl who has a boyfriend but she never mentions him. Of course I probably didn't ask the correct questions so maybe she never felt a need to. lol

The reason I ask this question is I've been talking to this girl for a while and only recently did she mention having a bf.
