Because you love your spouse, you really do wish that their life could be as wonderful as possible. You can do a part in making their life even better. Just ask what it is that you can do. “How can I make your day better?” Be sincere when you ask it. It isn’t manipulation or a tit-for-tat. It is caring that your spouse has a good day. Love is action – doing for the other.
When you ask how you can make their day better, you are saying is that you are willing to do what it takes to make your spouse’s day better – even if it means that you will be inconvenienced or put out. (And of course, actually do it.)
