Meeting sort of ex girlfriend, need female advice :)?

When I met my girlfriend I went to her house and we started to know each other, we have same personality and interests, and I really love her, but I was scared in the beginning when we started to go out, I kissed her when I came to her house and when I left, yap that was not nice for me to do but I was afraid of going to fast, but I realized that that was a mistake, she got mad and broke up with me and her birthday is this Sunday and I told her I changed and everything cause I did a lot of thinking, and she told me that we will see when we meet again. I'm going to her house on Sunday on her birthday, but how must I react, she told me I should show her I'm not scared and shy, but I'm a bit confused here. When I meet her can I still kiss her to show her I changes, and care for her, and what else can I do to show her I'm the man for her, cause if it goes well we'll get back together again, but I don't want to screw it up, should I act like I'm her boyfriend again and hold her hand, kiss her and hug her. Really need help with this one, need some female advice. Don't know how to approach this type of situation. :)
