How old are you both? Seven years is along time, and often it can be due to getting comfortable and in a routine, and so you do need to bring the passion and excitment back. You can do this in lots of ways...but what you need to figure out first is whether you still love her and are prepared to work thru things, or whether you definetely have no love left for her and are just with her because of convienience and not wanting to hurt her....if this is the case you need to end it because you will only end up hurting her further down the line anyway, so you need to break it off to give her chance to live her life...
