So your biggest faults in the entirety of you marriage was that you allowed bad behavior because you received negative attention from your mother and you were probably involved in a co-dependent relationship in which you were the one with dependency issues?
From a 30,000 ft view of yourself in that relationship and the relationship as a whole that's where you see your problems were? And absolutely nothing else?
Everything else was your exW being "a brat" or being "unhinged"?
