I have liked her all year and today something came up when we where on the bus and she was talking about some dress she got and then she said you I know you are not relly intrested and said that's what you get for having a girl friend and then she stopped for a few seconds and said you know a friends that's a girl and then she just went silent for a bit what does this mean should I ask her out or wait a little bit longer help

Don't read too much into this.

But if you want, and it feels right, ask her out.
