I get my Wife in a good place before she goes on her two night work conference. I don't want to give her any reason to be mad at me before she goes on that trip. Yes that is fear from me, based on insecurities that she will be in an alcohol party environment. I don't want to give her a reason to cheat on me.
Quick reminder. Nothing you do or don't do can control your Ws behavior. There is no justification for cheating. PERIOD. If she wants to cheat, she can easily manufacture an excuse in her head. You are still letting Ws crazy dictate your behavior. Let go, man.
