40's (M) married for 2 decades suddenly wants to be alone like wtf?
Help me understand why a married man wants to suddenly live alone in his 40's? We're married for 2 decades with 2 children. After the cheating issue which I discovered, he left and the only explanation I got was he wanted to start a new life, alone without me. Though he's still seeing our kids. Is this a mid-life crisis for men? Or he just wants out so he can continue what he's doing without feeling any attachment or guilt?
Tl;dr looking for an explanation why men suddenly leaves after being found out about his infidelity claiming that he wants to be alone.
