Hi Hope, One thing for sure, if you go to a typical psychiatrist or psychologist it is likely they will not diagnose Reactive Attachment Disorder (RAD) correctly. It is important to go to someone who works with people who have Reactive Attachment Disorder (RAD). People who understand the many ways it can manifest. Just as in any mental health diagnosis one does not need to have all of the symptoms to have the diagnosis. Usually it is something like must have two of X from part B and four of Y from part A and Z has to happen before the age of W...... you get the idea. And within that yes, there is a range of severity. Your guy actually sounds right up there with pretty severe in some ways. If you had a gut feeling he was involved with the birds, he likely was. I can think of times I was upstairs and my gut said something was going on and I ran down and found my son breaking something or whatever...no sounds....just had that feeling. There is actually a movie about a little girl from long ago where she killed baby birds.
You can search the internet for attachment disorder therapy and see if there are any clinics in your area. Bottom line is you can't arrange any of it, right? If husband buries his head there is nothing you can do except keep easy child safe.
