I agree with dday. I think it's fine to keep possibilites open. Maybe your W is just wanting to be friends. You need to do that anyway since you have kids together. But, if she were to want more and YOU also want more, then I disagree with the advice to give her the cold shoulder. I don't think you would do that anyway.
Everyone's situation on here is different, and nobody wanted to find themselves here (including me). One thing I have done, though, is I look at each poster's description. That will give you an idea about their "slant" or take on things.
For instance, dday's description shows that there ARE possibilities after divorce. If that's NOT what you want, then fine. But if it is what you want, I think it's great to be open to that.
