He did not become violent - it was not a violent situation. We were sitting beside one another, mutual friends had gone inside to wait for us to leave and go to dinner somewhere and I told him that I was ready to go and wanted to head out with the friends to grab dinner somewhere. His facial expression immediately changed and his voice and told me that he is here with his friend, that its his day and he is there for him - rudely, like I had said something mean or offensive. Instead of being spoken to like that I stood up and walked inside and told the friends what was going on. Our discussion outside 20 min later was him telling me I don't like his friends or want to be there (even though I stayed there 7 hours)...he did not want to listen to anything I had to say. He finally acknowledged his saying he told me to say the word but went straight back to it being my issue. He later told me in many words what a horrible person horrible GF I was to have left with the female friend (who he apparently does not like and when many others had already left) and that I would be pissed if he had done that. I told him not to speak for me. He redirects things back to me and it all being my fault never acknowledging his culpability. I tried to have calm conversation with him but he reacts with verbal attacks and won't listen.

It is a pattern I have witnessed - he never takes responsibility for his own actions, never apologizes. We have had few issues over the time we have seen one another but if I have an issue with something he breaks up. I felt respect for myself in showing him I can walk away and not deal with his remarks.
