Since our separation, the ex wife has been very secretive (controlling and possessive) about where the children are and what they are doing. She is punishing me and we both have lawyers. I used to take my children and attend their extra-curricular activities. She's changed the days and times so I can't attend. Yes not in the children's best interests. She is moving houses with the children (they told me) and won't tell me where to. She is deciding to change my children's schools without consulting me. Should I get my lawyer to send her a letter asking about all three items above?
