I'm not homophobic, or anything. I was eating with my girlfriend today, and suddenly, when someone stopped to talk to her, she snapped and instantly yelled "pronouns" and said she's gender fluid. I was shocked because I knew nothing of this gender thing and honestly hoped she was joking.

Not because I'm disrespectful to anyone in that group, but because it would be a boundary and a dating line I wouldn't be willing to cross because of my preferences.

I've been thinking about it all day and was planning on talking to her tomorrow about how it makes me feel uncomfortable. I'm also slightly hurt that she didn't tell me anything about this. I just don't know what to think; I really don't like making people sad, but I fear I might need to break her heart. And I'm devastated just thinking about it.

I really hope someone can give me some advice or opinions on this. (Sorry if my English is bad; it's not my first language, and I'm still learning.)
