Dan pretty much took the words out of my metaphorical forum mouth - the earlier you understand that attraction isn't a choice, the more success you'll have with women. When a girl doesn't 'feel it', she'll often be very indirect on how she 'tells' you - hanging out with other guys, not talking to you, etc. That said - anyone will feel like that after a long-winded relationship - I felt exactly the same. It's completely natural, but in time you'll see it from a different perspective. Don't mope about it - she dumped you, but dude, turn your swag on! Go out and have fun, take lots of photos. Party. Think of the fun you can have without her.
