<human>: A month ago, my girlfriend of two years dumped me out of the blue for another guy. I thought we had an awesome relationship, so I was blindsided when she dumped me. Ironically, it was her friends that came to my aid and helped me get back on my feet. Since the breakup, I've grown really close to them.

Anyway, probably like a lot of guys, I've always had a crush on her (very attractive) best friend. Over the past couple of years, I felt like we had a connection but ignored it because I loved my girlfriend. But now that we're both single, I'm strongly considering asking her out. I'm 90% sure she feels the same way. I think both of us are waiting for the other one to make the first move. 

We're supposed to hang out tonight. Do I try and move things forward?
