Is This Friendship?

After breaking up with my last boyfriend, many things started to change. People came up to me to tell me he was only using me, or he was a total jerk. Although they knew I still liked him, deeply from my heart, they assumed I was lying to get attention.
It makes me sad about how ignorant a person can be, how a girl that's 13 will not and can't forget a love even after 1/2 year of breakup...
