It is rough on them, and rough on us, too. My D went through a lot of the same things in regards to visits with her dad and the best I could do was be there for her and let her know I wasn't going anywhere. She also had a few accidents around the same age that were related to the trauma of the visits (I believe trauma is the correct word for what she went through - her visits were out of state and for 2 weeks at a time). What your son will remember is how each of you dealt with this, especially as he gets older. My D is 13 now and has a terrible r with her dad because he could/would never acknowledge her feelings surrounding all of this and how hard the visits were. Continue to be there for him and pray that your W wakes up and starts to acknowledge his feelings and will work to find ways to make the transitions easier.
