This is such an important point that applies to many dynamics-not just men/women relationships.
GoodAngel,
Ending things and moving on is hard.
For me, it felt like breaking a bad habit, iyswim. I had to change a reflex.
Another aspect, was like separation anxiety. I always associated that with little ones starting school, but then when my DF passed on I identified (a part) of my emotional turmoil as separation anxiety or abandonment. Cue to the present-as an adult, not a child, I did not need to sucumb to those emotions. I coached myself through it.
That was sort of an operational example of what AF said earlier about "Fake it until you make it."
Please do not trust anything your ex says or does. Presently, he is enjoying himself greatly having two women. Don't buy into it...you already know he will never be monogamous. There will never be peace in your heart, mind, or soul while you are with him.
His flattery is nothing more than a recruitment tool.
His rage is nothing more than being totally angry that he has to find someone else to USE and it takes alot of time, playing nice-nice, and money to break in someone new.
