my pretty childhood friend is being mean to me..what should i do?

[whitechoco]

i'm friends with this girl, Lani, on twitter. we used to be close before because we live in the same neighborhood. we hung out couple of times in the past before twitter was even discovered. lani is very pretty, but she has this DOMINANT attitude. she poses on twitter like she's a model, thinks she's better than others girls, and curses. there was this one time i posted on my twitter new pictures from graduation, i graduated with a BS in business administration just this march and for me this is very fulfilling. lani made a mean remark on twitter and posted "don't think ur better than others just cus u went to college, i can kick ur azs anytime biotch" , just like 3 hours after i uploaded those grad pics. she was certainly bashing someone again.

not that i have anything against out of school youth, but lani was homeschooled. she's 24 right now with no college degree. i got my college degree at 21.

there's nothing she should be insecure about, she's waaay prettier than me. has a hot boyfriend, who has certain "fling issues". i mean, lani if youre in a serious relationship with a guy why post pictures of u in a bra and panty showing off ur tattoos? and what the heck did i do wrong..i'm confused.pls help me out

when i would smile at lani in town, it's like she doesn't see me..
