There is a difference between bringing up questions and badgering...I have done both regularly. I have done both well!
Badgering is destructive, questions are constructive.
I am still learning how to question without badgering...so no valuable advice here.
I do offer this up...this is not a competition, this is not a game. It is not helpful to go in with the attitude....I brought it up last time, it is his time to bring it up now.
As Sisoon says...if you have a legitimate question, ask it. Give your WS an opportunity to engage you. Try not to get defensive...it is likely you wont like the answer or that the WS will even be willing to answer the question. If this happens DONT bring up the list of failures they have accomplished. It is counterproductive and is hurt that is unnecessary. Dang if I haven't done that.
My struggle really comes into play when my fWS says she is going to do something...then fails to do it. Such as respond to an email in 2 days....5 days later no email. I ask her about it...she apologizes and does it. I HATE those moments....but also realize my wife was like this all of our marriage.
This is tough. Realize all involved will stumble. Keep trying to engage...don't keep score of who is doing it more often.
God be with us all.
