Married for 23 years, together for 24, separated for 5 months and already filed. I was so devoted to my wife that I still feel guilty even thinking about being with another woman. My mind knows this is stupid but every other part of me cringes at the thought of ever being with another woman. It's not like my stbx hasn't moved on. Hell, she moved on while we were still together

Am i doomed to feel this way forever? Does this ever go away? If so, how?
