Smileless2012, it doesn't always work but usually the fallout is less unless you are dealing with somebody with a personality disorder or other mental health disorder. I have had to work terribly hard at not becoming estranged with my daughter who is BPD. Once I realised the path I was treading, which was definitely in the wrong direction, I read everything I could get my hands on to see if I could at least keep up some form of communication. There are times when it has been as much as I can do not to throttle her with her mindset but keeping things level has got us to a slightly better place. She is going to have treatment and I am reading the literature her CPN is recommending to her to see if I can understand her better. I am also thinking of doing the NVCC to see if there is something I can learn there too. As I say to parents of ASD or PDA children who complain that the powers that be are insisting they go to Parenting Classes before they will help, you never know, you might learn something. I know when I see my offspring bringing up their children, I often think if I had my time again, I'd do it their way.
The family were technically in therapy for a year but after the first session (and the other couple of sessions), the fallout was so great, it would take months to get everybody back. I think it is hard for any mother to hear that kids who she thought she would always be in great relationship with, were so unhappy with decisions she had made throughout their lives. Small things get magnified if not done with great care and you can get so bogged down in things that actually weren't the original problem. It just snowballs from there.
