So I seem to be the only one who finds that husbands ex always calls his parents/sits and chats / etc.

It is not our weekend to have his child but his ex says oh you can have him Saturday for the holiday. Husbands says he may have to woek and she then goes and calls his parents and says I can drop him off and you can have him all day. AND HIS PARENTS Agree!!! She always does this and his parents are always there for her like husband and ex never got divorced. It's been 10.5 years and still the same.
