This is a coming from a woman that has been there. If you have had an argument with her and she is now wanting space. my opion is she is not as close to you as you are to her she is looking for a way out. if you truly love someone you dont want space you want to be with that person all the time. i mean put it this way look at the the way you feel about her do you want space? yeah maybe sometime but not that much. It depends on how much time is spent apart and how much she puts you off.
