Exactly, Spero.
My own abusive STBEX, would try and sell me a 'sanitized' version of events with regard to his abuse towards his first wife, and would always insist 'I may have had anger management issues, but I was always a good husband and father...I was there for those kids, I was hands on'.
And when I had the temerity to suggest that regular smashing up of inanimate objects and the attack on his wife which led to her finally filing divorce (they were separated at the time and he half throttled her in their study in front of the 3 children) wouldn't win him father of the year award-and may explain his eldest daughter's resentment of him-he didn't like it! (I only discovered this after we were married)
Of course, I knew nothing about the level and extent of his past behaviour before we met. Save to an admitted 'capacity for anger'. It was hard to reconcile it all with the lovely man standing before me who treated me well. I thought if I was clear about my expectations/boundaries-ie zero tolerance for violence/aggression, all would be fine. I wanted to believe that via the extensive private psychotherapy, CBT and anger management sessions, he had done a lot of emotional work and was no longer "that man". He wasn't outwardly...til I married him and had his child.
DV/extreme volatility is always a CP issue. The way a partner/couple behaves and functions in the presence of their child acts as a blueprint for their future relationships as adults. It matters not whether the abuser-physically or emotionally is a man or a woman. What matters is the risk of significant harm-both physical and psychological to any child/ren unfortunate enough to be caught up in such an environment.
It's what finally gave me the strength to tell my abusive ex that I wanted a divorce-the physical abuse was episodic, but the emotional, sexual, psychological and economic abuse was far, far, more insidious. I did not want my 2 year daughter to hear and eventually comprehend her father calling me vile sexual swear words, calling me useless and denigrating my more 'humble' background. What I didn't foresee, as I made plans for my 'exit' is that he would veer from manipulate threats to harm himself if I didn't agree to stay with him, to seriously beating me in front of, and then when I tried to flee whilst holding my child, before abducting her.
I will fight tooth and nail to prevent ANY contact until their is a robust, forensic, psychiatric risk assessment of him.
