Mossflower; As I have stated before, I am no expert. I am thrilled that you had a good day with your girls. However, they are not the ones that will decide if your marriage will be reconciled, and you are no longer in a buddy's basement. Only you AND you wife can determine that.
The good things about shopping and playing video games with your girls, besides the fact you get to see the kids you love, is that it will help, if the "big D" actaully happens. If your girls want to spend time with you, then it will be easier to get visitation, etc.
Something that I notice, yes, as a girl, is how much you say you love your girls, but never that you love your wife. If the love is no longer there, a permanent split might be in the best interest of everyone involved. No sense in all being under one roof, and being miserable. Not healthy for the girls either. If the meetings are having to happen with a counciler, then really the best advice I could offer is not good. I would say take your wife out, on a date, like when you were courting, and you won each other's hearts. But if everything now is about ultimatums, from either side, or both sides, a date isn't realistic.
Do not feel the need to reply to this post. We all know that the less you post publickly, the better it will be if the divorce becomes reality. And again, it really is none of my business, but I just thought I would share my observations.
I am so glad that you and your girls had some time, and a good visit. I know that it makes your heart glad too.
