I always knew the truth would come out.

Well it all started about two years ago, my sister had been dating this boy for about two months but i on the other hand was kind of shy. And then all of a sudden i started drinking, making out with boys and altogether not being a good person.
But this all changed when i started texting this boy that hooked up with my sister, he was also a few years older than me one or two just, we started to get really friendly and i had started to think that maybe this could go somewhere, i forgot to mention that i didn't tell him who i was because i knew he would freak out if he found out who i really was, so i made up a fake name, age and i thought it would all be OK.
But he found out and so did my sister. My sister got over it really quick but he hasn't talked to me since then but then i fell in with the wrong crowd, who turned out to be this boy's best friend we began friends unbeknown to him who i was, as i used the same fake name but we didn't tell the other guy and all of a sudden they were both going steady with different girls. And now i find myself falling pretty hard for one of those guys little brothers. But he said to me the other night that we couldn't hook-up. I think i need some help? Tell me how to change his mind because i could see myself falling in love with this one.
