(Sorry Job, I still have not posted my thread but I would like to have the chance to offer my advice to Ben)
Ben, I understand why you have not filed for D yet, and I would have done the same if I were in your shoes. You still want to R (even though you do not feel the urge to do so), and you and W have reconnected these past few weeks, so filing for D now would be odd. Either you should have filed months ago, or you should wait a little to see how things go.
I have to agree with Steve on no R talks. Don’t bring up R and let her do it. I think you should make her work harder before getting back with her. Otherwise it would be just too easy for her.
Now, here is the thing : you are now spending quite so time with her every week just like friends do, and W has not even expressed the desire to get back together. As far as I’m concerned I think you are too available and should back off a little to make her try harder.
