You cant move forward and on to a new life if you converse in gossip with the other "nice" woman.
And you have to stop being shocked about what your X is doing. So he gave up fishing for now - he is in love and getting married - nothing shocking there.
I get the feeling, from what you write, that whenever you get a small amount of information about your X, you over analyze and obsess about it.
You must give up all hope now of wanting your XH to return. That is really the only way for you to change your life and have, as a side effect, the possibility for a rekindling some years down the road. He is not coming back any time soon.
