So good to hear that you turned your vacation around and had some fun! I am so glad to see you list the positives in your situation.
I know the fear you have in setting boundries. They will test you at every turn and you have to be prepared to stand your ground. Just make sure that your bounrdies are fair and realistic and then you can be sure that you have "right" on your side. ("Right" for you, your son, your H, and your marriage.)
