Don’t put it on the kids
Have you ever tried to get your bride to do something or agree to something you want to do, by saying, “It’s for the kids” or “The kids want to” or “It would be good for the kids”? Even if what you say about the kids is true, you are being less than truthful with your wife if you are not upfront about you interest. Besides, she’s not stupid and knows what you are doing – and think how it makes you look to her.
By the way, if she will only do what you want if you guilt her with the kids, your marriage has problems that need to be dealt with ASAP.
