This sounds like you are just friends with her, or she takes you as a friend. If she's telling you this kinda crap.

Ok so you want more than that. It may be hard to step out of the trap of just being friends. But you can always give it a go. Make her want you. Just be funny, spontaneous, and exciting. Come up with some ideas, take her to like the top of a big hill to watch the sun set. Drop in some sleazy lines and then have a laugh together about it.

I find most girls are totally boring and out of touch with the world. Show them how to have fun, don't ask them if they want to do something. Tell them you know this cool place and you are taking them there. Think outside of the typical dinner date. Don't even call it a date, just meet up with them and show them your world and what you like to do.

This way if a girl wants more, you will find out. There will never be an akward moment, everything will be clear to you. And when you get home they will come inside, they won't be able to get enough of you. They will start to undress you and they will want you!
