Women being in the workforce made infidelity more commonplace, I think. It made it harder to keep marriages going.
I know that I dont want to be in a relationship where i fear that my partner is going to cheat on me just because the opportunity presents itself.
To me, it looks like you are trying to find the logic and reason into why your W made these decisions. Trying to find the thing to blame so you can fix that.
In my opinion, those details dont matter. What matters is you. So what of those things that you were trying to do or considering have you actually done now?
