Wow, she's lucky to be with someone like you! Sounds like you are supportive, eager to learn, willing to look deeply at yourself, wanting to understand her. Bravo! I wish you both happiness. I know for me it was a relief to hear about polyamory too, since it explained my destructive past relationship patterns.
Now I'm going to google TEA and the exercise you mentioned. Thanks!
