<human>: I have a crush on him since we started to work together in september. We have a ton of things in common, he is very nice and funny and everything.. He has a girlfriend and as far as I know they are happy together. The guy doesn't flirt with me and I think he hasn't recognized that I fell for him. 

I'm in a relationship too, but I don't love my bf anymore, our relationship is empty. I'm thinking about breaking up with him but would that solve anything? How could I fall out from this guy, we meet every day and work together 10 hours in the office.

Can you condense the text into a few key points?
<bot>: Fell in love with my manager, but he doesn't notice me and we will never be together. How do I fall out?
