Sophie, my H filed and I am thinking it is better this way, because now he's going to have to face reality.
I too tried to be nice and got the melodramatic "No, no--don't get your hopes up for me" type of deal. OK. Think "Last Resort" technique from the book.
At this point, I am actually glad he filed because it means that he will be taking on more financial responsibility. I am exhausted and, like you, find myself getting quite tired being a parent of a very small child while H daydreams around and shows up when he feels like it. I am hoping that the preliminary hearing will make it crystal clear to H what D is really going to mean.
As far as D, I'm currently staying open to R but not sure if that will last.
Bottom line is that our H's have lots of growing up to do. I blame myself partly.
