Ok, so me and this girl like each other, but she has a BF and idk what to do, any help is nice

Ok, me and this girl (we're completely different ethnicities, I'm white,she's black, I' was the only white guy in an all black school)) have been talking for a 1.5yrs or so, we started off flirting A LOT, everybody knew we had a thing for each other (mostly because we were always together), so I asked her out, but nothing happened because I ended up getting sick & a week later or so into the summer I heard she had a boyfriend......ok, so during our sr year (this past year) we started flirting again, but this time more aggressively, we both always seen together and we started rubbing on each other (I would grab her ass and she would grab mine, etc.) and then occasionally she would kiss me on the cheek and stuff.....and then her bday came around & I was there for her when we & her friends went out, her BF didn't go, he was in trouble (he's 18).....so a few weeks after graduation was my bday, me and all my friends went out, she went too, and her BF tagged along, so the entire time he has his back turned were flirting again (playing ass grab with each other, hugging all on each other).......and then about a few weeks back, me and her and some our friends all hung out together and after she got dropped off at home, she called me, she said she wanted to have sex,and she told me that I turned her on, so I asked her if she was sure and she said yea, she said "well, I'm curious to what you would say to my offer and I really want to do it because you turn me on" my response was, "ok, I feel the exact same way, but if your gonna cheat on your BF and were gonna have sex, I would rather take you out on a few dates before we tore into each other" she said then said "that's what she wanted and now, she's is supposed to come home in a few weeks from school and we're supposed to spend the WHOLE day together and I'm taking her out on a date that night (I had originally asked her out for just that night, but she told me she wants to spend the whole day with me, which I feel is a plus), and her BF doesn't even know she's coming home or that we're going on a date.........what I need help with is, did I do the right thing, I am I on the right track to stealing this girl's heart and making it mine? Any and all opinions are welcome.......

Don't be the guy she cheats on her BF with. Wait for it. If she really does like you, things will work out good. Good Luck bro =)

Laloosh53 is right. People either cheat or they don't cheat. If she will cheat on her current boyfriend, she'll cheat on you.

Bro not cool! :( I'm begging you to NOT hlp this girl cheat on her bf. I can't stand guys or girls who cheat. Bro don't make that list. Dude if she loves you it'll work but please for the sake of God don't hlp commit adultry.
