Am I going to push her away

2 weeks ago my GF if four years asked for space. We ended up talking on Sunday and got together for dinner. We had a great time and ended up kissing pretty passionately in the car. She later text me that she was thinking about me. We went out for dinner last night. When I got to her house she attacked me, it was very passionate. We went out for dinner and it was a little awkward. I can see she still needs some space. When we got back to her house we spent the night together. I stayed over and left in the morning. I can still feel that she wants to be with me but is still interested in space. I feel if I don't call her she might think I used her. I love her and want to be with her but I don't want to push her away. Should I stop contacting her and let her call me.
