My friend Crystal has been extremely attached to me and I don't know why.
My name is Sean and I'm 17 and my friend Crystal is 16 and in my math class, recently she's been extremely attached and affectionate. Sometimes I see her at the gas station I frequent and when I talk to this one girl from school that I may have a crush on, she gets jealous and drags me out of the store.
I don't know what to do, can I get some help?
