<human>: I've been seeing a girl for like 10 weeks, 5-6 dates during this time period (crazy work schedules). lots of talking inbetween dates, we met on OKC, we have not slept together yet. 

I brought up the conversation of "where do you see this going / what is it you are looking for/exclusivity talk" tonight and she revealed that she currently has a boyfriend/SO/fuckbuddy/something-illdefined-of-that-nature that she has been seeing for 8 months but who she does not want to be with long term. This other SO knows she is looking for something else and is cool with it.

I am not comfortable with sharing her, she's a real catch (cute, phd student, same worldview, same interests) and this came as quite the shock as I had assumed (never assume) that she was unattached. 

We are both looking for a long term relationship but she says she is not comfortable with committing too early due to being suck in bad relationships in the past.

Can you summarize the given text in a few sentences?
<bot>: just read it. I'm not really comfortable getting more involved (emotionally or  sexually) if she is not willing to give up her fuckbuddy.
