So a reply something maybe like this? I'm sorry you feel that I am dragging this out. This is a big part of our lives and our kids lives and there are so many thoughts and emotions involved. I want to be sure that I am doing what is best for me and what I believe is best for the kids. It hurts me to think that we can only talk with a lawyer or mediator is present. I not sure how things got so far gone. But If that is what you want to do that is your choice and I will respect that. So we can talk at the mediator or whoever you want. However I am not rushing into anything without the properly thinking things through and talking to the right people.
Everybody hurts. It's part of life. Don't miss the good stuff.
