You can also find something you like to do. In love, you don't have to stick together all the time. He has his job, and you must have something you should do, whether it's school, work or something else. It's a good time to have a good rest or recharge your batteries.
Because two people must be together for a long time, and if he is busy at work, you can't be idle because he doesn't accompany you. So you're just busy all day for love?
Just use this time to find friends I haven't seen for a long time, chat with friends, and see what happened recently and how others are. Don't let love have everything for you. If you can't stay in love in the end, at least there will be friendship and work.
Or you can read books in your spare time, find some books you like, find a comfortable place and enjoy the rare leisure time. Even if your boyfriend is away, you can go to your favorite place and buy your own favorite things.
Or you can just make a gift for him during this time, on the one hand, to comfort his recent tired mood, on the other hand, to bring your feelings alienated by time closer. He will be very surprised when he receives the gift, and he will definitely think that you are a person who knows life, so that your's feelings will get better and better.
He will think that you not only didn't lose your temper with him because he was busy with his work, but also made a gift for yourself to comfort him, and he will be doubly kind to you. In this way, you won't quarrel over this matter, and boys won't think you are unreasonable, but they will think you are considerate and sensible.
