To start with, my roommate is Russian. She isn't fluent, but knows enough to get by because of her parents. I thought it was cool at first because occasionally she'll teach me Russian. Sometimes, however, we'll hang out with my close friend who is fully Russian and fully fluent in the language and they'll randomly change the language of what they speak in our three person conversation. I'll start to feel left out since they usually speak in it for about  two minutes so I  change the subject so I can get involved. Now an hour later when my roommate is alone with me she's being passive aggressive and I think this is why?

Tldr: am I an asshole for interrupting a conversation I'm not involved in because of a language barrier so I can be involved?
