That's it really. I guess it will depend on circumstances of split and pre divorce relationship, but I am wondering how this plays out in other families. My db has been split for the last 3 years, and our respective children are each others only cousins and ex their only aunt. Db does not want ex to continue to have any relationship with my children (or with me for that matter). Is this normal/reasonable? They had been together for 20 years and now both have new partners. Split not due to affair but long term breakdown of relationship, both had been unhappy for years.
