I need some help and not sure if this is the right place to go. My ex husband has totally disowned his daughter, but still intends on seeing his son. I feel that is unfair on my daughter as he lavishes his son with gifts purposely to upset my daughter when her brother returns home from visits. I would like to stop my son going over and feel that my ex should be trying to sort things with his daughter rather than sweep it all under the rug.
