Why is he still calling me?

So I figured new day new things right? Wrong! Ol' Calvie Boy decided to call me today. Ok so I am partially to blame because for one I answered the phone. I did act like he had the wrong number and hung up, curiousity got the best of me and I called back to find out why he had called. I got to hear excuse after excuse and appology after apology. I really do not know what to think. He said that he did it so that he could see his kids everyday and I don't know if its really the best thing for the kids or not because they are always fighting. He also let me know that she admitted to saying she wanted him back because he was happy with me and she was jealous. Well enough of this.
