I read your post on emotions and it was really helpful. I decided I need to read Radical Acceptance by Tara Branch but it isn't available in Australia so I've had to order it on Amazon. I couldn't even download it on Kindle.
I am a very emotional person (at least my partner thinks so) and dealing with my emotions is an ongoing process. Polyamory seems to trigger my emotions more than anything else, in my current relationship. I try to observe them, remember they are only feelings and that I can decide how I'm going to react. Things are much more peaceful as a result but I really think I need that book because I can't seem to maintain a state of peace for very long.
