Getting an ex back after talking

I got dumped 5 weeks ago and was still in contact with my ex trying to work it out. She would come over and we would kiss and she would say om making her decision so hard. On easter friday we had sex but she said we were still on the break. Sometimes I was ringingher and she still talks dirty on the phone last time I spoke to her last saturday night she said have you got a hard and I said maybe and she said well I've got hard oobs if that helps you out. I'm 28 she is 22 we were together for 3 1/2 years I want her back so bad I wish I hadof gone nc straight away she may have come bck by now do you think it is to late now for nc or should I just not speak to her again from now and hope. Our last time we saw each other I was at her house and she said to come to church with her, I then rang her that night and that's when she spoke sexually on the phone and I said I had a good night tonite but since we are on the break imjust not sure and she said well it was a it of a couple thing and I said do you like that and she said well its ok sometimes and I wouldn't of said to come tothe church if I didn't want to. At times I think she's ust happy to have me around so she feels better and not all alone I am going no contact now and it may be too late kicking myself, I think this may be the best way to get her back. The first week she said I have missed you a bit at night bt habvent called cause we re on a break. I feel if I'm not in contact with her she may miss me but feel she's had a month to prety much get over me now and I think se slowly is. But she did say come to te curch ad that was a couple thing and she spoke dirtyon the phone maybe se just likes to know I'm still there so confsed...
