My wife pulled the same crap on me. “ We just drifted apart “. Now I can actually understand why she did what she did. BUT , she blindsided me and all of a sudden, someone I was intimate with for over 40 years just told me to keep hands off and get out ! No explanation, just get out. People just don’t want to work on their marriage anymore. 50% failure rate. Whatever happened “ to death do you part “ ? Those words don’t mean crap anymore. I could see it under certain circumstances. But she had plenty of freedom. Maybe too much !
