Well... I for one was an angry person. In fact that was one of the complaints W had that actually held some water. IC and some books helped me get to the root of where this came from. I was a conflict avoid fixer... Which brings a nice dose of passive aggressiveness with it. I would do A B & C and expect X Y & Z in return.... When that didn't happen I would become upset.... It never would happen as I would learn, because W could not read my mind nor have a clue as to what I wanted because I avoided stating my needs to her .... Huge issue in our M that was all in me. This was one of those things that I listed and replaced with becoming stronger and not afraid to confront people in my life and state firmly and verbally what I expected/needed
As far as anger from the betrayal/abandonment ... That's normal and will be cyclic... Comes at you in various wave of intensity ... When you learn to grow you can harness this negative energy and use it to propel you past a point where you were stuck... In the detachment area for instance ... Some times it give you a boost to leap forward ... Accept its normal and all part of this, don't live there ... But don't deny its place in all this either
