I read the show online and was moved to tears. My deepest sympathy goes out to all of Caitlin's family and friends suffering through this horrific tragedy.  
After reading not only this discussion board but many and reading through various messages from women who are suffering or have suffered at the hands of an abusive partner, I felt the need to post. Women going into and in new relationships need to respect themselves and have the courage and ability to recognize these potentially abusive men and get out while they still can. I'm finding it difficult to find the words to relay exactly what I'm trying to say but this I know: 
When a man tells you how to dress yourself: that's a red flag 
When a man tells you how to behave: that's a red flag 
When a man (not the father) tells you how to raise your child: that's a red flag 
When a man tells you where you can go and how long for: that's a red flag 
When a man doesn't let you see your family and friends: that's a red flag 
When a man trys to control everything you do: that's a red flag 
It's not an expression of how much they care about you: it's control. And they aren't going to change or get better, they are going to get worse. And I think alot of these men that we hear about that do these terrible things have enjoyed and needed the feeling of control for so long in their relationships, that when they lose control, they simply can't handle it. And in a perfect world, every parent would have the abilities and tools to teach every child about self respect and how to let and not let people treat you, but sadly every parent doesn't and every child doesn't grow up vowing to not be controlled or disrespected by anyone.
