Dont know where to begin.

In spring 2007 i met this girl. Met her in a disco. (Lets call her: dani)
The day afther we had a sort of date so to speak, and played some game of pool. Thats how it all started.
When it is weekend and i intent to go out, i mostly go out with her.
She and i are both sort of players, and in the mean while i had a short relationship with someone else, that was a while back.

While going out, sometimes i go home with someone, and allso other way arouned that she goes home with someone.
So we are friends, allways laugfing, and if we had a fight, few weeks later i see her again and she tells me how mutch she missed me and all is well again, like the fight never heapend.

This is what i know of her/ or what she told me so far.
-I allways want to be single, Dont see a man in my future. (maybe becouse she is still young; her age is 19 (i am 23) that maybe why she thinks this way)
-Things that i see of her is that she has a big wall around her feelings, So its hard for me to open her up.
-Thats she is happy with me becouse most guys just want to fuck her, And that i am one of the rare people who dint share this thing.
-When she stays over at my place for the night and we sleep next to eachother, she allways wants me to hold her. putting my arms around her etc.
-Everytime if a guy opend up to her and showing that this person was in love with her, she imidiate pushes this guy away.
So i am afraid that will heapen to me.

Maybe more things will pop in my head soon i dont know.

Anyway from spring until now alot has heapend. Going out alot. She even asked me once to become roommates (if i had a job en she on school in a specific town).
And we even slept with eatchother a couple of times, This case she dint push me away.
But then again i never showed that i was in love with her.
Last week she told me, this is great, we are good friends, do nice stuff together, and if we feel like having sex, then we do it, no complecations of a relationship..
At some point i agree with her, My relationships so far dint last verry long (exept for my first).

Ow yeah, before i forget: if i show intrest, that she gets the feeling that i am in love with her then she does a step back (so to speak) And if i pretent i am not intrested at all, then its like she is in love with me.
With most guys she can control them like: do this or do that.
I am the oposit, She likes playing boss. And i never take orders.
Sort of power play.
So now i have sort of discribed what kind of relationship we have..

So what i exualy want is for her to open up to me if something is really bothering her (One thing is for sure, i am a good listener).
And would like to take the thing we have more seriusly then just friends.

Anyway have some good advice?
If you need more details or have specific questions just ask.
Maybe it wil break things down..

Good luck reading my english. hehe
