The problem at hand:
I have a girl who I have worked with for a two years and hooked up after a work event for the first time three weeks ago. After this point I knew I had a timer running to hook up with her again or loose any shot of it. Additional info she has a long term boy friend who she lives with and she recently infromed me she had a long term affair with my bosses boss while she was with her current boyfriend.
This past week she informed me her boyfriend wouldnt be around this weekend in passing conversation and I figured this was my one shot for a second hookup and to finally sleep with her. We went drinking with everyone at lunch, then went for drinks after work with everyone, and then I got on the train with her to head back to home and we decided to get some more drinks. Instead of going to a bar I dropped some negs and convinced her that her empty apartment was a better place for drinking. Once there things quickly escalated and we ended up sleeping together in her living room. She loved it and made comparisons to how my skills were both better then my bosses boss and her BF lol. She had friends which were enroute to her aparetment from previous plans and just as we finished her friends hit the building buzzer stopped by her aparetment and pretty much caught us getting our cloths back on because we were both drunk and she let them in before I was fully dressed.
I peaced out pretty quickly once they got there only because I actually had dinner plans with another girl and since this was all unexpected I didnt want to blow the second girl off. So I left around 6PM.
She then proceeded to be totally drunk out of hand the rest of the night and had the cops called on her around 3AM (who she apparetnly sat and talked to topless for 30 minutess).
The following morning she called me up and having a moderate break down about how her friends think shes a hore and her neighbors think shes nuts and asked me come by to console her and to bring her the morning after pill. I stopped by we talked, I found out her BF wont sleep with her and hasnt paid attention to her sexually for over a year, and this whole incident is showing her that she needs to deal with that or break up with him, but that she pretty much has her life planned with him and besides there lack of sex hes a good BF. Also, she has no idea how her life would work without him since she lives in his place in a yuppy town and blah blah blah.
Anyway I eventually peaced out and texted her later just to see if shes good, which she wasnt but she asked me to just forget about everything, which I agreed to only to help her out but have zero intention of doing.
So my question is this, I want this girl to be like my girl what do I do next? We have now hooked up once and slept together once. I do have a side girl I am seeing which I want to and plan on jettisoning reguardless of how this goes but I could use to help me with this if needed. (I have told side girl repeatedly that I dont want her as a GF so I dont feel bad about using her because she doesnt seem to care)
History for those intrested:
I meet this girl two years ago just after I broke up with my Ex, after starting my new job. I weighted 230 pounds at the time and now I weigh 170 and I am pretty much have a marathon runners body (which is how I lost the weight).
She oddly is my female advice giver if that makes any sense, when I date girls or see them I ask her for ideas and stuff like that she knows most of my sexual history and dating history in detail for the past two year peroid which has been pretty boring up until the past 6 months.
Additionally, while she became one of my closest work friends I never paid attention to her sexually because she leads guys around like their zombies and shes shes the only living being around. Shes the hottest girl in my company of 200 people and I knew two years ago if I ever wanted a shot I couldnt let her pull that on me or else I was done(this wasnt some big two year long plan it was just someting I always kept in my head). She actually pointed out to me right before we slept with each other that she always thought I wasnt into her and it bothered her.
