Glad to see you are still plugging away with Headspace. I went on a pretty treacherous bushwalk yesterday (lots of potential for rolled angles and a steep section called "heart attack hill"). I swear I was so much more aware of where my body was at as a result of my mindfulness practice. It was awesome!
Andy Puddicombe (the Headspace guy) also has a good podcast on relationships. Helped me detach and come to recognise my H as his own person in the early days post BD. The link below is for iTunes but you can also find it on Soundcloud (called Headspace on...relationships).
