<human>: Give me the gist of the text in a nutshell

Hey there, Reddit.

So I have been talking to a girl for about a month now, and we've become really close. When I first started talking to her, she had a boyfriend (who happens to be a friend of mine). 

I've grown to resent this "friend", though, after hearing from her the way he treats her. We've become very close and she is now on a break with her boyfriend because she wants to give us a shot. He... knows nothing about it. Did I mention I also work with this friend and see him just about every day? Yeah there's that, too. 

I really like this girl and, in any other circumstance, wouldn't hesitate to pursue a relationship with her. Do I tell my friend what's going on? 

Do I not even bother trying because it'll get too messy? There's quite a bit more to the story; if there's info I need to fill in before any advice is given, I'll gladly provide it.
