How do I get ex girlfriend back if I'm the rebound?

Before my relationship with my ex girlfriend she dated her previous boyfriend for two years. He cheated on her and treated her really bad. I think that might make her want him back even more but idk. She said that she is not in any position for a relationship at the moment.

She has hung out with her ex and she has even been over to his house but still I don't know what she wants. She says that she doesn't want a relationship but she talks to and hangs out with other guys and sometimes acts flirty. Do girls hang out with other guys just for the sake of hanging out and nothing more?

I heard that she would consider dating me again after sometime but in the meantime I don't know how to act. If I am the rebound from her previous relationship before me how do I get her back? Ignore her? Try to stay in the picture and remain in contact? I need advice because I am really confused
