I was also going to suggest that you read “The Garden of Peace” and you will gain an attitude adjustment. Usually women turn into “nags” because they are NOT respected and listened to the first 10 times. If they are respected and listened to they don’t turn into “nags”. The more a “wife” is respected and acknowledged the more she respects and acknowledges.
Women burn out because of fatigue and hormonal changes and if there is not positive input via love and attention then we sizzle and burn more easily. The more positive energy put into the relationship from a loving, caring husband, the less likely the wife will burn out, nag, get moody, depress, etc. Men and women are different and it is up to YOU OP to realize that and learn to appreciate the differences. Isn’t it interesting that your friends are complaining about the same things? That’s because YOU are all the same. YOU are all males, and your wives are all female.
