That certainly is bizarre. Is there actually a child? Did the man and his fiancee have a child? Is the woman the biological molther of a child.
Too many unanswered questions.
Due to confidentiality, we may never know... but you got me thinking, assuming that both coupled actually did have a child, and assuming that the recipients both had M.H.'s sperm, those children would be biological half-siblings. Theorhetically, they could be back in court in 18 years trying to find out who their brother/sister is...hoping it's not their boyfriend/girlfriend - I know, odds are slim to none on that last one, but this whole situation raises SO many more questions than answers.
I've got to believe there is a child. Otherwise the "mother" would demonstrate that there's no controversy here and that M.H. should leave her alone.
