What do you do when your crush is a lesbian?

So there was this girl who served as a waitress at a bar I like to go and drink and watch soccer. She’s is really beautiful with a superb sexy body. I mean the kind of body that should be walking a run way and slaying them fashionable trendy clothes while paparazzi take photographs of her. I still remember the beautiful smile on her small oval face when I told her she was better off as a model than a waitress.
I have had my eyes on her for a while and I always teased her and complimented how beautiful she was. Then one day, after my team Arsenal beat Manchester United 3–1 in a premiership game, I was in a good mood and a few liquors had gone down so I had a loosed tongue. I walked up to her, and we got talking. Actually I did most of the talking as she just smiled and listened.
I wanted to know about her. I told her she was my crush and I was interested in taking her out so we could have a great time. I complimented her looks and she was full of smiles. I also found out she was reserved and even on the shy side. This boost my momentum because I showered her with all manner of praises as a sharp sweet mouthed guy that I am.
Suddenly, I proceeded to ask her about getting together and starting some kind of relationship. This was the part that broke the camels back. She looked me in the eyes and responded by saying “I don’t do relationships”. I was shocked, happy and surprised because in my mind I was thinking well, with all the smiles on her face, I can see she likes me, but if she doesn’t want a relationship then am more than willing to be just ‘friends with benefits’.
But I didn’t want to leave anything to chance so I asked her why? And she gave me the shock of my life. She responded by saying “I have a girlfriend”, and then it clicked. She told me she was a lesbian and she lived together with her partner. She also confirmed that they were in some kind of open relationship. I was still surprised because in a million years I wouldn’t have guessed it.

I told her I was shocked by her revelation and I thought she was rather bold, beautiful and mysterious. This made me want her even more because of the air of mystery she had about her. I asked her what her thoughts were about going out on a date and she promised to give it a thought and get back to me.
I am yet to get a response from her. I haven’t been a relationship kind of person but I wonder if anyone out there has been in this position before because if not for anything, I would like to have better chances of predicting the outcome between me and this mysterious beautiful lady.
What would you do if it were you?
