You need to talk.. Properly.

You say there are signs.. Does she hide her cellphone? Has she recently changed hairstyles and got new perfume, and more expensive sexier lingerie? Is she late home after telling you a certain time, on a regular basis?

It might just be paranoia on your part, due in part to the lack of intimacy and you might have seriously hurt her with your emotional accusations. I think you need to find out if there are other reasons for your wife's lack of interest in sex with you.
