She Drives Me Crazy!

So at first i thought she was hot! we went on a night out with friends,things got a little heated but we work together everyday so nothing happened. We got to know each other more and more, shared our life experiences and i fell for her and i had never felt anything like it, i just wanted to be with her all the time, to maker her happy when she was sad, i can't describe in words how i felt but it was amazing! anyway one drunken night we slept together, it wasnt mind blowing we wer both drunk.! anyway we stayed flirty friends we talked about our feelings etc she told me she knows women aren't for her and she wanted to be with a man. I love her so much and i still have to work with her everyday, its torture. she's said she will just stay out of my life and i know for my sanity thats the best thign to do but i love her so much the thought of her not being around hurts aswell. i dont know what to do??
