Sounds like shes not physically attracted to you anymore, plain and simple. If thats the case, there may not be anything you can do. Sometimes once the fire is gone, its gone.
Gllllll. Sorry I cant offer any quality advice here, but Im kind of on the other side of the fence here. Was with my GF for 15 years, and my attraction just got up and went, so I left a year ago. I still think the world of her, but physically, Im just not into it unless Im really drunk (we hang out sometimes, and once in a while we will have teh secks because of alcohol, but thats about it)

You might want to pick up a Bible. God ordained marriage, right there in Genesis. Monogamy is as old as mankind itself; "spreading your seed around" is as old as sin itself.
