Gwen, I agree with all that 25 years said - I have used a life coach, and I realised that although (from my perspective) my marriage was happy I had changed parts of myself/adapted to be married.

I still believe at the root of an abrupt and unkind departure there often lies emotional abuse, and simply dealing with that as trauma can help. It initially helped me, and others, who do not necessarily post here.. I then did life coaching etc from a less damaged place.

And many years on my xh is still unhappy, still searching for the answers. And I feel great!
