Glad to have you as a neighbor Deep. I, for one, look forward to you hanging out over here with us. I find it a huge help to talk to others who are dealing with the same issues and love getting insight from those who are further down the path.
I'll echo H4U's sentiments, you're a bigger person than me dealing with W's continued working with OM. I have read your Newcomers thread so I understand why, I just know that I could not handle it. If OW had not been laid off by BF's company there is no way we would be back together now. I was glad to hear that your W made it clear to her boss that she would not work with OM once she returned from maternity leave. She is choosing your M and her actions back that up.
If you love somebody, set them free. http://tinyurl.com/2empx2g
