Hi, so im pretty new at this, and would like to get your opinions on this really messed up 5 way love "triangle"

so heres the situation: there's this girl that im going for, lets call her cami, who some months back i helped my bro out with, and i actually got my bro and her to kiss but he was super lame with her and she doesnt want him anymore.
mean while, by helping my friend i really started to want this girl, and my bro is now less and less interested in her but i think he actually thinks he's got a chance, witch he hasnt, believe me, i know.

so it would be easier if it was just my bro, but the night we met with this girl, i actually drunkly hooked up with her best friend, but it was just a fucking 2 second kiss, just because she had been insisting the hole night. this was like more than 6 months ago.

like 2 months ago i got this girls to come to a party in a friends appartment. beautifuly played. this was the night i got my bro and cami to hook up. also, this was the night her best friend started to hate me, because i didnt pay attention to her, and also because i kinda hit on another friend she broght. (keep in mind: cami's best friend is a 4 or 5 at most. my bad.)

cami does know i was going for the other girl, but it was ok because she was with my bro that night.

ok so to the point. a few days ago i asked cami out, she was with another dude, and she also blew me off because i was with her friend, fucking 6 months ago! just a kiss for gods sake.

so now i know she left her guy and is single, and we've accorded to party toghether soon, when she comes back from cancun.

what the fuck can i do? is it even possible for this thing with her to happen? she has shown IOIs specially the night i hooked her up with my bro.

what do you guys think?
