Is it swallowing my pride or being the bigger person?

I am 24 and I stood up for myself to my boyfriend's parents about how they mistreat me and that they over-step their boundaries when it comes to my relationship with their son. Now for the past few months they ignore the fact that I even exist. My boyfriend and I are taking a break from college this weekend and going back home. He wants me to hang out with his parents and act like nothing ever happened even though they will be spiteful and shooting bitter, underhanded comments at me the entire time. What do I do? I would like to be in the same room as them but they deny ever being rude to me and tried to brainwash him into dumping me. It is ridiculous.
