I have to agree with bohemiangirl85, I think it's time to end this. I read your thread yesterday, but I had to take some time to reply because it reminded me of a non-relationship I was in. It was a lot like what you described, things going well for so long, then a big fight and nasty things said, then we'd make up and things would be fine again. He also kept me along as a "booty call", even while dating several other women. I firmly believe that this man I was involved with was a narcissist, and was abusive towards me. I know your situation might not be as similar to mine, but if it is I think you should get out now, before you get hurt worse.
