[header] How to know if a girl is playing games with a guy [title] Ask her how she feels about you. [step] There are a lot of ways you can try to read the signals, but the easiest thing to do is just be upfront with the girl. Ask her if she really likes you, and don't be afraid to say that you feel insecure about it sometimes. 
If you do this constantly it might get on her nerves, but there's nothing wrong with asking her. Don't accuse her, just say sometimes you worry.
