What does it mean when she...?

so im a couple with this girl, but it rly doesn't seem like it, i mean literally everything has to come from me and Angela(her) seems so emotionless, when were alone she can just stand in front of me and do nothing, i rly have to initiate everything and it's like she just goes with it.. Like no.pion.at.all. And it makes me uncomfortable and it seems angela can only like say what she feels/wants with text messages, not in real life. What should i do, i rly don't like it like this. . . And ye i tried talking but she's super 'closed' ya know. . I want pion . . .
