Detaching is so much easier when they continue to spew the mean, nasties and deny their role in healing and/or harming the R.
Hey Bridge,
Glad things are going well with you. I just want to chime in with one note of caution. It may seem easy when the X reinforces why you left, but in reality I think it's not so clear-cut as that. Conflict is an attachment in and of itself. By holding on to that finger-pointing, justified as it may be, you're still holding on. There is as much of an attachment with disappointment or anger/hate as with love.
The thing to strive for is not feeling the need to comment on it anymore. To let that attachment, and the associated tally-card of who did what, go - frustrating as that may be. Trust me, I had to learn to do it with my parents and then with my XW. Until you learn to truly accept that it was what it was and to let it go, you'll never truly be free. Leave that completely behind and trust solely in yourself now.
Not trying to be a wet blanket on your progress, because it seems like you're doing great. Just hoping you don't get into the morass that I got into.
