It is important to include your spouse in important decisions. You are equals and interdependent in the relationship and each of your perspectives are important. Ask, don’t tell. Especially if you want your spouse to be a willing participant.
Ask: “What do you think about …?” “What do you say about ….” “What are your thoughts about …?” “What are your views on …?”, “What do you suggest?” “Where do you stand on this idea?”
Asking makes you slow down and consider that others may have some valuable insight. Then, listen with real curiosity. Shared thinking usually produces even better ideas than you might come up with on your own.
