I have no idea what meaning it was for my W, but apparently my W's favorite song all last year was Adele's - "someone like you"
All I know is that the words to that song, and the context and theme of that album, were about Adele's personal experience of leaving a relationship and this particular song being about how she still loved her ex and the things about him, wished him well, and hoped to find someone "like" him... even though she did not go back TO him...
The point is, I believe there is a consensus that many of the MLCers and WASs... really is that they want to "erase" the LBS and anything that might remind them of the LBS, simply in order to not have to deal with the healing process around that specific person...
That by erasing and finding new friends, new homes, new jobs, new lives... their hurt and pain and perhaps... the things that they might work on themselves to make better or "fix"... they avoid...
This appears to show up a lot in MLCers, more so than in WASs... It still appears that way with my W and so many who post in this particular forum, here...
Like a OP... I think while the avoidance is still going on, there can be no healing and no reconciliation... regardless of how that might work, either as a reconciled M or simply as a "friendly" relationship and healthy co-parenting...
If your W was and / or is MLC, then IDK... but I'd say that when you start seeing her trying to reconnect with people she's avoided... discussing the past in a civil, logical way... being different and more "parental" with the kids... like I said, IDK... but I suspect you'll notice those changes... then and only then might you consider that she is starting to come out of the fog... like I said, if she's in MLC... (not saying she isn't, just pointing out the disclaimer)...
