You could always try to reconnect with her, if you want to stay with her. Try going out on dates again, even if it is just once a week, or get that facebook contraption, I heard its a great way to stay in touch with people. That is, if you want to stay with her.
as for breaking up with her, there are quite alot, some trollish, while others are serious.
