My really good friend was flirting with the girl he knew i liked?

i like this girl named hannah and we've talked a lot. and most of my friends know that i like her and might ask her out. i usually talk to my friend brett about her. and one day i was running with hannah and brett. (me and hannah usually workout together) yah so i was talkin to her n then brett interupted me and hannah and brett just started talking for the whole run. and right after wen i was changing brett said man i no wut u mean about hannah shes really nice. n i was like o well dont get any ideas. u no i like her. n then he said yah i no. so about a few days later he said hey austin im going to give you 3 days to ask her out before i take her. and i freaked on him i said man ur my friend u dont take a girl from them. n then he said o well it doesn't matter much. so then i said k fine. n tonight i was over at hannahs house n we were all going to watch a moviebut i had to go back to my house to get a movie. and i didn't notice it much but brett and hannah were talking the whole time. and it started to piss me off. so hannah left the room for a sec. and i got up n freaked on him i said why the **** u flirting with her? n then he gave me a lil smile one of those y smiles n he was like shes nice man. i thought brett was a nice guy but i guess not. so brett kinda started to show off a little bit. he started doing tons of push-ups. and sh!t like that n she started to get impressed. brett is a tough guy. hes very musclualar and most of his muscle he got from his dad because his dad was a big body builder wen his mom had brett so most of his muscle is natural. not that any of it matters... so yah wut can i do? i really like her. n its not the kind of like where its cuz u haven't had a gf in a long time so u just want one just to say you have a gf. its the kind where ur alike. hannah likes working out. having parties. sports. smokin up. were alike in a lot of ways. (the stuff i said wasn't it) so wut do i do?!
