You are 100% correct. Wife says the best way is to get away from them.
This is actually shocking to myself. And yes I am now a Trump supporter, was a Carson supporter and leaned towards Cruz till the Chicago thing.
Wife also says they are the ultimate in lying. Wife also says that she knows of no relationships that have survived these types. And that is after 35 plus years in the field.
You either get away or completely shut down.
Normal interaction is completely impossible with those people.
