Is he going to tell everyone I'm obsessed with him?

Okay so I’m in 9th grade now, but back in 7th grade i had this friend. I really really liked him like that and it was really pathetic I basically thought I loved him and stuff. I talked about him all the time as well. Just your stupid normal over the top first crush. But he somehow heard how much i liked him and got this idea in his head that i was obsessed with him and still am. It’s been 2 years since I’ve talked to him and he hasn’t crossed my mind at all. My cousin got a class with him this year and she knew i liked him, she’s a sophomore and he’s a freshman so she was like do you know (my name here) and he said yeah she’s obsessed with me. To which my cousin replied “Not anymore!” So is he going to run and tell the whole school that he has confirmation i was obsessed with him?! I’m really afraid that this is going to ruin my life!
