It does sound like you need at least a break from your family. Do you go to counseling yourself, or would you be able to? I don't think its a bad thing if you don't want you children in the middle of an adult situation, it just breeds more problems, and may ruin the childs friendships too, if they are close to them. Well you're moving anyway? I'm sorry to say this is a lifelong delimma you will have to go through making this decision with the new people too? Trust your own judgment too!
