Okay babes! I need serious analyzation.
So there is this guy in my chemistry class, who, as far as I know, is straight. He has been going out with the same girl for three years. However, he is always really nice to me and I catch him looking at me a lot. I tried to tell myself he wasn't, but today I just couldn't deny it. He smiles at me when me make eye contact (whenever I make eye contact, which is rarely cause I'm scurred to get my heart broken

) and he laughs at my jokes, but so does everyone tbh. He knows I'm gay and idk what to do. I need someone to tell me how to know for sure. HeLp
