However, I would take whatever you think is best for you and the kids. So, if you think this offer is great, I wouldn't let you hoping for R get in the way of taking it. Yes you may R but you also may not and the terms of the D will stick by you and your children. If she's being friendly and willing to be amicable I personally would take it. As many say divorce is a piece of paper.. You two haven't been living the married life for awhile now.
And I apologize if I'm coming off harsh I just wouldn't want you to pass up a good setup for D over the hopes of R. I would hate for you to wait and things turn nasty and you end up having to fight tooth and nail for custody, etc.
