Ok first off you said you are dealing with child abuse issues. When you are dealing with these issues you are going to have more ups and downs. It felt like and still feels like the worst roller coaster ride of my life when I deal with it. So my first question to ask is are the family members the ones that caused the abuse? Are you uncomfortable about them having contact with your T? If so I would suggest that this is not a good idea, it may violate the trust relationship established with your T. There are other T's available to speak with your family, I'm sure your current T can suggest someone that they can speak with instead.

It's nice that they are having some interest in your healing process. I'm also sure your T can provide them with a list of books that will help educate them so they can assist with your healing. You should also discuss, ahead of time, the boundaries with the T, if you plan to do this.

Hope this has helped and good luck in the future. Remember these are very hard issues to deal with, so take periodic breaks from this subject so it doesn't re-traumatize you in the future.
