Abuse and Hormones
Question on Reddit
Testosterone is known to make people more aggressive. This has nothing to do with being abusive.
My son used to point me at people who wronged him when I had PMS because I was ready to leap on any excuse to express righteous anger. It did not make me an abusive parent. It made me a hyper protective parent.
Don't go back to an abuser. The abuse gets WORSE, not better, because they figure you will put up with it and they tell themselves you love them and need them so much, you will happily pay any price.
And nothing you say about "I like x, y and z about you and would like to have that IF I can get it without the abuse." ever sinks in. Actions speak louder than words. The act of going back will outweigh anything and everything you say about what you want.
