On the custody: does your W really want to be able to come to an agreement between yourselves? It's not possible to tell that from what she wrote. She states you can't, but doesn't say she wishes you could.
Actually she states that we can't seem to come up with any agreement. Maybe I'm looking at this thru rose glasses, but the word seem takes some of the edge off of the word can't. I feel like she is still willing to try to come to an agreement.
I read on HeatherG's thread a post by NYSurvivor about a book he read on validation called "I Don't Have to Make Everything Better" by Gary & Joy Lundberg. I've read the first 3 chapters and I think that it will help me with validating WAW's feelings of missing DD's, but at the same time leaving responsibility for the problem with her.
I'm thinking of a reply along the lines of I understand that you want to spend more time w/DD's. I'm willing to share some of the time that, since our separation, they have been solely with me, but I still feel strongly that they need to start and end each school day from home. This way I acknowledge her feelings, acknowledge that I am willing to negotiate, but keep my boundaries in place.
