Boy Trouble: guys help!!!?

ok, so my boyfriend and me don't talk that much because our school is gay and we don't have the same cles so i only see him at lunch and recess (i'm 13 and so is he) and well this girl in his cl was telling me that he doesn't sit at our table anymore cuz they kept making fun of him and i laughed at him and this girl keeps telling me all these things that happen with them, like "yeah, we were like talking through the whole cl!" she's totally trying to make me jealous but i can't take her anymore, i want to know if the reason he doesn't sit with us is cuz of me cuz i love him! and i wanna get rid of that girl!
