How long will it take a guy to understand a lady?

It has taken me 45 years with my wife and I still cannot figure her out but I do take care of her and treat her well and try to be courteous to her daily. While I'm driving she likes to tell me how to get to point a to point b which I've been doing for years without her instructions. I'm beginning to think she's losing her mind.

When I'm with a new lady in my life after a while, I sort of understand her.
God also can't understand ladies how come a man would 😅
Never going to happen; it is impossible for guys to understand women.
