I'm just past the 6 month mark since bomb. The biggest thing I would have done differently would have been to work harder at consistency in what I said and in my actions. Too often I reacted rather than giving myself a day or two to think about what had been said or done and then respond in a manner appropriate to my beliefs.
Second, I would have given myself more respect. Too often I bent over backwards to try and please W without valuing my own needs. I think this is why "loving detachment" was so hard for me - you have to respect your own needs in order to detach.
Thirdly, I should have been more aggressive with the LRT. I tried to make dates, etc. for a long time before I finally adopted the LRT. This allowed W to cake-eat in a big way and for a long time.
Lastly, I probably should have exposed A to W's family so that they knew the real sitch and that I was willing to fight hard to save things. This would have given me a lot more power earlier. The family found out anyway, so not saying anything didn't do much for me.
One clarification - I don't regret anything because I've never been in this sitch before, just wish I'd done it differently.
