I think different dual relationships have different levels of DRAMA.
I know this one SLE-Se/IEI-Fe relationship where there was a lot of "You can't talk to this person", "You can't talk to that person" going around and it spilled over to everyone.
But they are now having a child together, but have distanced themselves from other people they used to know.
Meeting and having interaction with a dual isn't like a magical experience, but it will probably change you.
