You can observe what your boyfriend likes recently. For example, he likes a character's skin when playing games recently and has not made up his mind to buy it. Or maybe he suddenly fell in love with a game machine recently. Or you often scrimp and save, and haven't eaten a big meal for a long time. It is ok to have a big meal.
Sometimes boys don't care about birthdays. For them, it doesn't matter much whether this birthday is over or not, because the birthday is just to make them one year older. Especially some boys don't like extravagance and waste. But they may change their previous views because of a gift you gave them. That's my boyfriend. I thought my birthday party would be great. Later, I would give her some small gifts every year, and she would especially look forward to her birthday. So sometimes a person's preferences can be changed. It depends on what kind of personality your boyfriend is.
Boys generally like roller skates. They feel most free on the roller skating rink. So it is ok to send a pair of roller skates. Or your boyfriend travels a lot, you can also give him a suitcase with better quality. You can also give him a bracelet made by yourself. Or send him a blessing, hoping that he will be safe, in fact, it also has a good meaning. You can also give him a pillow with pictures of you two on it. So that he can take it with him when he goes out. Seeing the pillow reminds me of the happy time you had together. If your boyfriend works hard, you can also give him a massager. This can make him relax after work, and sometimes a massage instrument will relieve a lot of work pressure.
