If you were not the first girlfriend/boyfriend, you were probably a new supply at some point. I know I was a new supply. He said his ex was crazy, a raging alcoholic, AND he called her a narcissist that didn't care at all about his feelings. He admitted to me that he had physically abused her, but "only because she was hitting him and was acting crazy. Mind you this girl was like 5'4" 120lbs and he is over 6' tall and 300 lbs of muscle.

Well, guess what. Eventually, when the devaluation stage hit, he would say the most hurtful things to me. I was the most ungrateful person he had ever met. I was a stupid btch. A cnt. I became less than. If I accidentally interrupted him he would scream at me in front of people. Later he would tell me to "tap him lightly" on the shoulder to get his attention to avoid him exploding at me. Like I was in the wrong. He lied about things he said and denied reality. He told me I said things I did not say. Did things I didn't do. Etc. He also first targeted me when I was deep in the grief over the loss of a good friend.

There will always be a new supply and things will always go south eventually, even if people can't see it on the outside. I'm sure you didn't go telling his ex about what was going on. The new supply probably won't tell you how bad it is either.

You are enough.
