What do you think ladies?

My now ex g-friend and I dated for over 3 yrs. In the past year she has walked out on me 3 times...the first time was for 9 months, of course I waited on her to come back..and she did. The second time she was gone for 4 wks.......and then came back. And now it has been a week now. My question is this.......the first 2 times she left.....i basiclly begged her back.and she took her time.. ..this time....i just didnt really care. I stopped texting, calling...u name it. Now she is texting me asking if im already seein someone........and why im bein a to her. Im not being a ....i just dont care anymore I told her. Ladies opinion from personel experiences......if i keep up the tough guy act...will it drive her back to me in a fluster.....or just push her away???
