Song I think understand how you feel. I have not updated my thread in ages, but I think I can so relate to you.
After my H filed for divorce in 2013 (bd was 2011). We never really stopped seeing each other, even though I moved out into my own place. We still did everything together. I felt we were reconnecting, which we were.
We remained in a relationship for almost 7 years afterwards.
Until I realized it was not working for me. Yes he was out of his crisis and never found an ow, however I saw changes in him.
I still saw some selfishness he never had before and still some depression.
I saw the house I loved and left in disarray. His priorities had changed.
I finally had to leave, that was 3 years ago. My XH was just not the same man I married.
I still have love for him, probably always will, but the relief I felt when I finally walked away was huge. Like a weight had lifted off my shoulders. I felt so much more at peace with my decision and I never looked back or regretted it. He was just not my old H anymore.
You may or not feel the same way after you leave, but for me is was the best thing I could have done. It just freed me up.
I still have no desire to be with someone else, but my life is really good. Will I someday meet someone else? Perhaps..only time will tell, but for now I am happy.
I can only wish that for you, Song.
