No, you are not being unreasonable at all. In fact, if it were me, I would speak with an attorney and tell him that I have a job lined up in another state and want to move there and take the girls with me. Just see what he says. Since you and your husband are not divorced or even legally separated, I believe you have the right to take your children with you, so long as you aren't hiding from him. Ask legal counsel about that.
But, to answer your question, no, you are not being unreasonable and it's my opinion that you give him way too much input as it is. But, that's just me.
