can I get my girl back

My and my ex are now apart. she broke it off with the phase, I,m Done!! There were problems with her kids in that i didnt think they respected me and so I wasnt involved as much as I should have been. I had mentioned that they were to enabled and thats when she lit into me about she will enable them all she wants and If i dont like it tough and then It was, I,m Done. Now she will not answer any phone calls or return them. Can I get her back cos there was underlying reasons why I shut down. I was with this woman for 2 and a half years and she told me she loved me maybe 5 times in all that time. I paid for everything and I mean everything. Did she ever love me???????????? Can I get her back????
