You can take this for what is worth but what I have found out is that if a girl says she needs some time that means she has a lot of decisions on her plate... I would simply send her a text and say I understand and leave it at that... do not call her do not text her do not chase her what so ever... respect what she wants... if she contacts you then answer the question and that is it... dont be cold but just answer her question... you now have to let her do the work and see if this is what she wants... if it is she will start to talk to you more and more and eventually she will ask you to do something... right now all you can do is be understand, be patient, and keep yourself busy until you see what cards she is going to play... I hope this helps and like I mentioned this is only from my experience...
