Is it normal its taking to long ?

I met her at work, didnt knew anything about her, we was talking from time to time and smile to each other, it became more serious and we are almost everyday spending the all night togheter, there is weak moments and strong moment,most of them are strong. we are having a lot of fun and know pretty much all about each other.

Now, one of our first going out, we drinked a lot and it was very flowing.. we was hugging, laughing and touching all night. it was unforgettable night.

In the end of this night, i was driving her home and tried to kiss her, she was very quick and didn't even though about giving me a kiss in the cheek... it was weird, eventually we kissed in the cheek and i felt crap cause i expected more. it never took me so long to kiss a girl. and i never had a serious relation or any girl i really like. all girls i met was stupid and nothing for me. just making out and good bye.

ok so i thought maybe i just need to give her time so i did. we met a lot after that to, talked about relationships and almost everything, we never talked about me and her together and we just keep going out all the time and its ending kissing her on the cheek, thats so fucking annoying and it makes me mad, I really afraid it didnt became like "a good friend" and not getting closer to be her boyfriend..

she treats me really good and always takes care about me, she dont act like a bitch at all.

every day i thinking about giving up on her even though i like her a lot i really dont know any other girl like her, and i'm sure she likes me to.

should i talk with her about it ? about us ? i dont want to freak her out.. but i really want us to become more than what we are cause i think its just going to end in the cheek every time we meet. i start to fall in love and it can hurt me, and i hate to get this situation!

What should i do about it ? how you girls can to analyze this situation..?

Thank you for help people :)
