Girls i need advice please help?

Hey there ladies. I need advice...me and my ex broke up 2 months ago. We still keep in contact we talk on phone we text each other. I ignore her calls and texts and she keeps looking for me. She calls me and asks me some obvious questions that I give obvious answers. But I guess she calls me just to hear my voice. When I call her or text her she ignores me and pretty much mimics me. She came to see me we kissed told each other about our undying love for each other. But now were on the same square playing phone tag. Also im still in her family phone plan and still have a year left on the contract. When I told her over the phone I was going to disconnect the line she broke down in tears and told me not to abandon her. So ladies im confused what should I do? Im ready to give it another chance with her and also im ready to let her go just need a little direction opinions are opinions but again I need your opinion here to help decide. Thanks ladies for your time is very appreciated.
