I'm sorry your boyfriend has an ignorant room mate. Just ignore him. It's likely that he won't be the room mate for very long, and even if he is, over time, your actions will show that you were serious.
My fiance's brother was our room mate for a while and it was when I had just started losing weight. He would say terrible things to my fiance about my weight, and then talk about how 'hot' other thinner girls were. He would give me dirty looks when I ate 'bad things' not understanding that this is about moderation not crash dieting, but I ignored him. Finally, we had a huge blow up, and we weren't room mates anymore. My fiance and I moved on, and didn't talk to him for quite some time. My point is, I kept going. We have all since forgiven each other, but here's the thing: I have the satisfaction of know that I kept going, and the last time I saw him, he seemed legitimately surprised that I actually stuck with it.
I'm not saying that you should do this to impress your boyfriend's room mate, but my point is if you just keep doing this for you, and ignore the snide comments and just keep doing what you're doing, then eventually your actions will have proven that you were damn serious and that their words had no effect on you.
You can do this! Ignore the jerks!
Don't ever let anyone else tell you who you can be
