WW confused about the future.

[excile101]

I have been trying to keep busy. My job takes up long hours. I have just enrolled to finish my degree in engineering. I am planning on hitting the gym soon but there is an emptiness in my life I can't fill.
Last weekend was a killer. I saw the kids and took them out but when I gave them back, the lonliness crept back in. I contacted my w as I hoped to see the kids again that evening. She refused. She told me to stop using her and the kids as my company and get a life. She even suggested that I should GO AND LOOK FOR SOMEONE ELSE! I couldn't believe it. She says we are finished and that I had my chances and only wants to be friendly for the sake of the kids.
When I pick up the kids, she is ok but not very talkative. She messages me alot but only to tell me about the kids. I keep things civil when I am with her but nothing more. I am trying to detach but seeing her makes me melt. I cannot avoid not seeing her so end up pining for her.

She is reasonable with me but isn't interested in anything else. I don't contact her and let her get in touch. What else can I do here? To tell me to move on with someone else is not my objective. She knows how I feel about her so why would she say that? So confused now....
