Is NOBODY wrong in the post ? POST : Currently a junior in high school on the soccer team. I generally try to be friendly with my teammates but I would not say I'm not in the same "friend group" of the majority of the team. Last week, I heard them talk in the locker room after practice about my girlfriend's friend and talking about how they thought he was gay. I wasn't really sure what to say or do so I stayed out of the conversation and left. 

After that, I went to meet my girlfriend and I mentioned that my teammates thought her friend was gay, not adding my opinion about it. She told me thats he's not and that I'm stupid to even mention that. I wasn't sure why she was mad because she generally wants me to tell her any type of gossip that floats around. I told her I didn't really have an opinion on the topic and that I wouldn't care if he was or wasn't and just mentioned it because its considered "gossip". She said she was sure he wasn't because they go to church together and she knows him well. I tried to move the conversation along because I didn't think saying that was going to be a big deal but she left and ignored me for the past few days. AITA? 

If I am the AITA, is it because I perpetuated this rumor?  She also knows that I generally don't hang out with the team unless for practice and games.
