Angry - about interaction

I have had problems with a person attacking me personally during meetings and infront of other people at work. Yelling at me. Saying things about how they had stereotyped me ...and how I can't get or do certain things because they believe I am a certain way. The behavior was getting worse and worse, so I had a one-on-one with the person, and that made it worse. So I escalated it to my and their manager. It was several months of on-going discussions about this behavior before to my surprise the person was much better and more professional, willing to listen to me and allow me to give input without attacking me. At my review time, I was taken down one level, because of my relationship with this person, When I pushed for more feedback beyond that I was told that I handled everything well but but the general perception outside of my department was what brought me down a level. Now, this persons behavior sometimes is getting to be borderline again, when I voiced my opinion today in a meeting they get upset and tell me they have more senority then me...etc. And therefore my opinion on a technical topic isn't valid? I am struggling really with not feeling angry about this, about how their behavior is escalating again, how my boss does nothing, how if I say anything again I might be docked next year about it. I just don't know what to do. **Trying to be vague here about the interactions while still getting the idea across.
