I consider my self bi curious and I have this one friend who I really like but she says she's straight even though she acts gay. Like she's always holding my hand in class and telling me that she loves me, I just can't tell if she likes me or girls in general.She also says stuff like "that's so gay" or "I'm so gay" in a demeaning tone like that would be a bad thing, then if someone brought it up she would brush it off. Idk I'm just getting really mixed signals. What should I do?
