I know mumsnet is generally anti step parent and pro step child. No matter what. Now everything I’ve seen with regards marital advice with blended families is that your spouse must be number 1. Now I can understand how that may be extremely hard when your DC are still children but when they reach adulthood, should SC expect to be prioritised over their step parent? And should a parent stand by their spouse or child?
YABU = Spouse comes first
YANBU = Adult child comes first
