Is their sexual tension between me & this girl?

[pO]

Ok me & this chick met 2 years at a party we helped throw for our friend. She pulled me, she was so hot! We clicked immideiately & later that night when we were drunk we went in the house & i felt her up & we had oral sex.
NOT ACTUAL SEX & I REGRET NOT DOING IT. We stayed friends, i kinda had a little crush on her but she had a bf. everytime we would see each other, their was a just a feeling of sexual tension between us. Fast forward to a couple of weeks ago & the word got out about what we did at that party the night we met. She got mad at me, unfollowed me on twitter, deleted me from facebook... Etc. then like 2 weeks ago i saw her a t a part it felt ACKWARD & SHE WAS WITH HER BF (same guy) & SHE WAS STARING AT ME THE WHOLE NIGHT! i wanna tap her so bad! How can i tell her i know she wants me & hit that?
