well dont just spring it on her. move in slow and watch her face, mainly her eyes. unless your more comfortable asking. I used to have a big problem with making any kind of move and still do at times. do whatever you feel most comfortable doing. if she didnt like you she would spend time with you so if you ARE moving too quickly the worst respose will probably just be her telling you to take it a little slower.
hope this helps. keep us posted
