So just when I start to detach and stop holding out hope, more comes to me. I just got off the phone with my divorce attorney who had just spoken with my H's attorney. Apparently my H's attorney is extremely pro-marriage, and at some point in time in the past had an affair and his wife took him back. Now he and his wife go around to churches and other groups talking about how to save your marriage. So his attorney is going to talk with my H about what a dumba** he is being, how much he is going to lose by going through with this divorce etc. He's also going to encourage my husband to move out of the house so he can experience the full brunt of what being divorced will feel like.
And our interactions have continued to be confusing. We're trying to act normal in front of the kids, and then as soon as the kids go to bed we go our separate ways. However, he is trying to engineer more time as a family - he is leaving work early tomorrow to come home so we can all go to the movies as a family, then he wants us to take the kids bowling on Saturday, as a family. I told him that he could take the kids to the movies on Friday, and I would take them bowling on Saturday. That we need to spend time with the kids separately. He didn't seem too happy about that.
He's also doing other weird things like cleaning up the kitchen after dinner and loading the kid's breakfast dishes in to the dishwasher, none of which has he ever done before (at least not in recent memory).
