I haven't known that since the last thread. You're the only person who has, thus far, claimed she wasn't his girlfriend.
When Rachel Jeantel was first brought up in this case, she said she wanted nothing to do with it. Then she said he was her boyfriend. Then she changed her story again.
So any confusion related to her relationship with Trayvon is entirely her doing, and no one is exaggerating anything to ridicule her. She said herself she was his girlfriend, then retracted the statement, so the fact is no one really knows what her relationship with Trayvon was.
