Counteracting the Interference

The letter to my sd's therapist (or former therapist as of today) went out in the mail asking for a report from her on sd since the ex is ignoring hubby's email asking for details.  I hope this doesn't turn into a big deal. 

The ex knows hubby has legal custody and has access to all this information.  Why does he have to jump through so many dang hoops to get what any NORMAL and RESPONSIBLE parent would provide to the other parent? 

How can the ex claim to be so dang worried about sd to hubby but then leave it at that?  Does she think dad wouldn't care at all?  Not want to know what exactly is wrong?  What has her counselor recommending a psychiatrist over a regular therapist?  She feeds him little tidbits and then lets him hang there not knowing what the heck is wrong with his daughter.  It ticks me off!
