I've read through your story, and while I'm just starting out on my own journey, am impressed with the way that you continue to handle yourself. I myself am going through a similar situation.... W gave me the 'ILYBINILWU' speech 3 weeks ago...a bombshell to say the least.
We're working through it, but like you, I don't know that she'll have that fire for me that she once had. Regardless, your approach to life as it is now is quite inspirational as I begin myself. I've done all of the classic blunders in 3 weeks....pleading, begging, reasoning, snooping....all of it.
Like you, I think I'm finally at a point where I can step back and begin focusing on myself rather than focusing on something I have not control over.
If you have any insight/suggestions on how you completed this transformation, it would be much appreciated.
