A few days ago while at work, my boyfriend kissed me and his friend walked by and said, "Hey, quit dipping in my kool-aid." My boyfriend laughed (not humorously, more like "ha ha, shut up") and said "I don't think so man. This is my kool-aid." I gave my boyfriend a weird look and he explained that it was an inside joke between them...and by his friend saying that, it meant he was into me. I rolled my eyes and said his friend doesn't like me like that. Since then, they've been very rude to each other, giving dirty looks and muttering snide comments. My boyfriend even told me to quit being so friendly with his friend...and the friend confronted him and told him to quit trying to control me. Their friendship is totally ruined right now. I don't understand what I did...but I seem to be the reason they're acting like this towards each other...since all of their fights involve me. What can I do to fix this?
