tell them she loves them, do her own thing, and pray for them. . . Eyes often open up eventually, if you give (panicky) people time and space.
I'm not seeing a contradiction here. They're either her enemy forever, or . . . not so much. We're not God, so we can make our best guess, but we don't know the future. I don't see how she loses, whether her family stays deluded, or gets on the sane train.
I have plenty of wacko-birds in my family. Some have gone from "enemy" to friend; some haven't. I've been wrong plenty of times. If I spend my time trying to maintain an "enemyship" in my mind, I'm using up brain-space, and probably sinning against charity.
The problem is we are not talking about an intellectual disagreement.
As you might have guessed, I had this issue with my parents after I left the nest.
I told them my boundaries, and said do not cross them.
They crossed them, and I was done with them—forever.
I have a sister who forgave them and prayed for them and visited them and then faced emotional abuse over and over and over again.
Her call—but I will have none of it.
When people say they own you, believe it and run!
