Thank you all for your replies. My sister is also dealing with other issues with her ex partner and her child. They had both agreed to NOT introduce their son to new boyfriends/girlfriends/lovers... Since separating almost 4 years ago her ex has exposed their son to about 5 different "soul mates". Now she is also dealing with a six year boy that believes men should have a new mate every month. Visitations with dad has never been about spending time with the boy, its always with some woman always tagging along and staying at his apartment. Can a judge put a stop to this?
