Best example of how to estrange a partner from family?

He was brought up in a bubble- Perhaps he moved from one bubble to another-

Perhaps all he has done is traded one cracked environment for another-

Yes I do as well. He did put himself on the line (went bankrupt as I understand it) to pay for her very exclusive education.
Thought the world of her I understand.
Maybe he invested too much of himself in their relationship, but is that possible?

It's very easy to manipulate some one who loves you isn't it?
Into cutting out the people who would see your behaviour for what it is.

Why is it so hard for some people on here to accept that all a manipulator has to do is mirror the right behaviour, love bomb the victim, and exploit the cracks in the original family relationship?
All families have cracks nobody is perfect.

I do see certain parallels in my own situation with my daughter, who was very close but is now semi-estranged from the family since meeting her husband. There seems to be a familiar pattern in play. Obviously we can't know the truth of the situation, but I do feel sorry for Mr Markle, who has yet to meet his grandson.
