I lost my gf and best friend of 3 years because I was emotionally abusive
In what way were you abusive?
I was emotionally abusive to her. For example, I insulted her all the time, but she deserved it.
It's wrong to abuse people significant to you. You should seek help from a professional for your intemperance.
I don't care, I feel better now and it's not like she was the only person in my life.
Nonetheless, it is cruel to emotional assault your partner as it hurts them deeply. Treat other people the way that you would want to be treated.
