My GF won't answer my calls or Text messages?

Monday June 30th, was talkin to my gf, all of sudden messages just stopped, that whole week she hasn't answered my text feared that my text messages havnt been going through, then she wouldn't answer my calls, well finally that sat, she tells me we are fine, i know i shoulda taken that as we are good, but i kept texting her, and now i fear that i made things worse, she didn't tell me she wanted space or anything, did i truly messed up and caused my gf to break up w/ me or is there still a chance. would she have told me she want to break up if she wanted to?
