advise

Yesterday my ex had asked to take our son on holiday...i have turned him down but explained why to him which you will see in my previous post.
There are several reasons im not comfortable with the idea the main being my daughter and her current behaviour.
My ex text me last night and said say sorry to our son not him.
My son has returned this morning from contact and my ex has already told him about the holiday and times without getting the ok from me.It was like this last year as well he told my son to pack a case 3 weeks before a holiday and we were moving at that time as well.
Where is the co parenting here,if he dosnt get what he wants he badmouths me to the child.
Nothing was put in statement of arrangements about holidays and i have expressed my concerns about our daugher to him!
He makes my blood boil!

If he is good enough and trusted enough to have contact with your son, then why not to take him on holiday too? If your concerns regarding your daughter are that severe then surely contact should be stopped or his father should only have contact with your son without the daughter being present?
