too cocky, now i need help

ok, here's the situation, there's this girl, and i used to really like her, but things didnt work out, so we became really good friends, and it's been like that for the past 2 years...

anyways, just a few days ago, i starting talking to her on msn, and then she suddenly exploded on me, here's what she said, (and btw, it's on msn, but it's a fact that it's definitely her, and she was definitely serious)

"everything is perfectly fine with me.. but something is wrong with u"
"ure still the dam show off that u wereee"
"u think its ok to show off and everything in front of mee... but im juss tryin to stand u"
"and now im telling u"
" cant stand u anymore"

well, those words really got to me, and i was shocked when she told me, cuz i thought we we've been really good friends.

so i sent her an email, i told her everything, including how i used to like her. and of course i apologized too.

so then she sent an email back, and apologized to me about what she said, and she said all that because she just found out something about another close friend, and that she says that she stills wants to keep in touch me...

which brings me to where i am now...

i have no idea what to you, just that if i just be myself and talk to her, i'm worried that i'll come off cocky again and piss her off, but if i have to constantly think about what i say to her then i'm not really being myself.

btw, i honestly have no idea that i come off "cocky" in front of anyone

Jam it back in, in the dark.
