So sad, Yogagirl... so sad...
I'd love to think that no one could have brainwashed me into cutting off my parents. We had our issues, but there was so much good, as well, and, of course, lots of love. I can see opting for more "space," and I did, at one point, but completely COing them? No.
But I guess if you (general) are around certain people every day and they keep talking your parents down and giving you "reasons" why you need to break away from them, it could happen... shudder... Again, I'm so sorry...
About Joshua Coleman - I watched the video, too, out of interest. And read some excerpts of his work online. I agree it's very good though I worry about the idea of continuing to contact an AC cuz of concerns about a RO. I'm also not sure I buy the idea of AC cutting parents off, just to show that they're adults. That sounds to me like a dad who still hasn't fully accepted that his DD is an adult, even though their relationship is better now. When I sought more space from my parents, years ago, it was cuz they weren't treating me as an adult and I needed to get away from that to clear my head and figure out how to handle it. It wasn't to prove to them that I was an adult. And DH and I had our own home and so forth, so it had nothing to do with that. If I had CO them completely, it also would have been to remove myself from the situation, not to make a statement about it.
But that's me. I realize it may not be the same for everyone. And I'm NOT suggesting that anybody here failed to treat their ED or ES or their spouses as adults. Just expressing how MY experience differed from what Coleman is saying.
