1 month and counting?

Well it's been just over 1 month since she left me to go back to her ex and make a better life for herself and her kids. I had not heard anything from her in 21 days and then all of a sudden I got emails from her. We started talking again and she even talked about how much she missed me and how much she thinks about me. I emailed her back gave her the lowdown of what's been going on, and that I wanted her to help pay 1/2 of the bills for the house we shared b4 she left. She basically took that as a threat, and that I didn't care about her. She gave me a brief lowdown of what's going on with her and the kids, she got a "good" job and has a good future with it, as if to gloat a little bit. I wrote her back and said thanx for the info and I said it gave me a bit of closure I needed to move on. In a mean way she said here's your closure...good luck. I have decided to pay the bills myself and move on it's hard still but I have to. Do you agree??
