What to do?

So what do I do? She tells me that she needs time, that we should take some time and think about things. She will not talk to me. I don’t want to act like a stalker but I went over to her place and she did not come home for the hour that I waited. She will not return my calls, of freaking course I can’t email her (no computer). I should act strong and just wait until she is ready. I can’t believe that she is doing this.
