Haha, life can't be rough. Although you are middle-aged, you can't do without the necessary sweetness and romance between husband and wife. I have a few suggestions, ladies can adopt them:
1 I don't know if he likes chocolate, you can DIY chocolate gift boxes on some gift websites, and write on the chocolates what you think is meaningful blessings for couples. For your age group, it is not expensive, but very warm and effective.
2 Men generally like things that symbolize status, such as watches, belts, lighters, mobile phones, and these products with taste and grade can best give face in front of colleagues and friends. If some gifts are really expensive, you need to prepare and save money early.
3 If the time is right, you can take a vacation together, and you can take him on a trip, which can also enhance feelings and deepen understanding. It can also cultivate one's character, and it is definitely a brand new beginning after the vacation.
