Is it over for me?

[Yoyowife]

This has to be the hardest thing I have ever done in my life. It seems everytime that we spend time together it just makes it harder on me afterwards because I realize how much I miss him. I'm sitting here crying as I type this. I know that I need to stay away from him, but my heart doesn't agree. It is approaching 6 months since he left. It has been such rollercoaster ride. He acts like he wants to be around me then he gets distant again. He didn't do anything tonight to make me feel that way, but I had to talk to him about a car insurance paper he brought by for older D and I could tell he didn't even worry about seeing me tonight. I didn't let him know that I was hurting I just talked about the subject at hand and got off the phone. It certainly doesn't help that the OW is his secretary that he sees everyday. I just feel so hopeless sometimes. Any advice would be helpful.
