<human>: Can you summarize the given text in a few sentences?

So I've been with my fiance for 7 years but we now have a nearly palpable hatred of one another and theres a very high chance it's going to end soon regardless of outside attractions.
Girl at work has been what I believe to be pretty flirty with me and I didn't think anything of it at first but have been thinking of her more and more recently.
It seems pretty clear that she's into me joking around a lot telling me about how she's going to break up with her boyfriend, even so far as telling me about her favorite types of porn. 
The porn thing kinda threw me through a loop though cause now I'm not sure if she's just uber sexual and doesn't really have any real intentions towards me.
There was one time however where me and my fiance walked into work in the morning together and the girl said good morning to each of us one after another in very different ways, first to my fiance just a flat normal good morning and then a deeper sexier good morning to me which I know I didn't imagine because my fiance commented on it once we were alone. 
Anyway not really sure what to do should I continue to flirt and try to get somewhere alone with this person?
I guess either way my feelings for this person is just illuminating how unhappy I am in my current relationship but I probably shouldnt end things by cheating on her ugh life's hard and I'm confused lol.
<bot>: Unhappy in relationship girl at work maybe probably is into me idk whether or not to pursue it or if there's even anything to pursue.
