Do you fear that she may be having an affair? I get this sense after reading your post. Yet in a different post (different topic) you also mentioned that your sex life with your wife is very good. This seems odd to me, because as a woman I find it very difficult to have sex with my husband if I feel unconnected. Your porn addition (reference from a different post) may have caused your wife to distance herself emotionally from you. Many women feel unloved and rejected when they find out that their husbands fantasize about other women. It injures them deeply, and they have a very difficult time dealing with this revelation about their husband's secret lust.
