Your husband is really a three-good man, and your family life must be very happy and harmonious. You can record every bit of your happy and joyful time with your husband, and then design it yourself, add some creative elements, and make a record book. On your husband's birthday, give it to your husband to accompany him to recall. Isn't it very warm and romantic?
You mentioned that your husband's work is very tiring, so why don't you take your husband to travel together? Let your husband take a few days off, and then live in a place with beautiful mountains and rivers for a few days, recalling the feeling of being in love, your husband must be very excited.
Of course, there are many kinds of gifts. In fact, the most important thing is to look at your husband's preferences. If you give him something he likes, he will be more satisfied. If the gift is too flashy, I guess your husband will not be too happy.
