I'm a 53 year old male, my brother was in a cult, as was I, but I want nothing to do with them now, but he?

You know, I give give you a lot of psychobabble, but I know it is horse feathers. None of the techniques seem to work for long when you are trying to manage your feeling with your ow family. The best thing to do is to ignore t and "laugh it off" as if they are "goofin' on you". You have to be strong in your own beliefs and figure that "they know not what they do". This method may cause pressure on you, but hold the course. It will avoid hard feelings and keep the tension at a single level. Maybe someday they will realize their error, but don't expect it. Don't let it poison the life you have made for yourself and your wife.
