Great responses above.
I guess there is really nothing that you can say to your parents that will make them WANT to be a part of your lives. Listener said it best, they couldn't even sign with love. Yes, WT does break up families but the family also goes along with it.
I came across a quote today. I thought about responding to a family members shunning of us but thought....why bother, it will make NO difference to them. I'm sorry that you are feeling the effects of the shunning. Hang in there and know that so many here have been and are where you are now. Hugs to you.
