I was only with him for four months and had ended the relationship, but then I was pregnant and tried again for a month to give it a chance for the baby's sake. That's when he started to get physical and I got out. I had family support and I was lucky to be able to do so.
It was years before I could take a shower or clean the cat litter box without hearing him yell at me because I was doing it wrong and I was disgusting. During many of those years, I was with a supportive and loving partner (my fiancee and the dad to my daughter), but I struggled to commit to him fully because of the pain caused. In just a few months, he caused damage that took years to recover from.
I try to explain this to my daughter without making him a "bad" person. He is her biological father, but I can't risk having him in our lives again. Not for her sake or my own.
Narcissism destroys, and it happens quicker than you would expect. The wounds take a very long time to heal.
