I'm going to write as if what follows are facts, because it's easier that way, but it's almost all opinion.
It's not that healing is mutually exclusive to D or R. I think of it this way: One can...
heal and R
heal and D
not heal and R
not heal and D
I think perhaps the bigger choice facing a BS is to use the opportunity to take charge of his own life or not ... and I guess I think one can't take charge of one's life without healing.
So what's healing?
IMO it's learning to accept the A without defining oneself as a Victim in a Drama Triangle. Another way of saying it is that healing is the process of reclaiming authenticity after being betrayed by one's partner.
What does look like IRL?
It's really hard to see unless you can see deep into someone's being. R could be healthy, when it's a conscious choice based on seeing that the WS is willing to do the necessary work, but it could be unhealthy, for example if the BS can't/won't let himself consider D or if the BS ignores the fact that the WS talks nice but acts nasty.
D can be healthy, for example, when a BS determines the WS is not a candidate for R, but it could be unhealthy, for example, when the BS chooses D as a way to avoid dealing with his pain.
'Cause the pain at first comes from being betrayed, and every BS has to deal with that pain.
(A false R dumps even more pain on the BS, of course. IMO, if a BS heals some and observes his WS for a decent period, he's a lot less likely to open himself up to false R than if he commits to R based only on sweet talk and on his own desire to R.)
I don't mean to offend anyone here. I'm not arguing for or against D or R. I'm arguing for BSes to do what they need to do to become their best selves and to live their most authentic lives.
A subtext, I admit, is that I do believe some members have sold themselves out by trying to avoid their pain, which IMO is impossible to do.
I don't mean that as criticism. Rather, I mean it as a call to them to look inside, figure out the kind of life they really want to live, and then take action towards living the life they want.
