Rejection is no fun. When we get rejected, we make note of why and try to avoid a repeat. Over time, this leaves us with a distorted view of our husband or wife, because a good percentage of rejections have nothing to do with us or what we asked for.
The distortion keeps us from even suggesting things we would enjoy. It prevents us from offering some great Third Alternatives when we disagree, too. So be sure you re-test your beliefs about your spouse's preferences from time to time.
Sex play that a newlywed woman turns down in her twenties might be more than welcome in her thirties or post-menopause. Our bodies and our needs change over time. Ask again, gently.
When you proposed that photography field trip and got that resounding no a few years ago, maybe it had nothing to do with photography or field trips. Maybe it had to do with a sore ankle or the argument you two had about bread pudding. Don't miss out on a possible shared hobby that includes exercise and nature and beautiful views: ask again now.
You can do this in reverse, too. I have a garlic allergy, so when given a choice between two restaurants, I seldom choose the Italian one. My husband simply quit even suggesting Italian restaurants, even though he loves Italian food. So I checked out menus online and found one to invite him to recently. We both loved our lunches, and "Patty doesn't like Italian food" was updated.
Remember that only a fraction of your earlier conclusions will be wrong now, so don't expect a hearty "yes" to every suggestion. Take the risk of a "no" or two to refresh your relationship and add more fun to your lives.
