If you find that your boyfriend is not romantic at this time, don't be angry, let alone lose your temper with him at will. You should teach him patiently. First, use your own actions to drive your boyfriend. You can give your boyfriend some small surprises on some small festivals and every moment of your life, so that he can see your attitude. If it is carefully prepared by yourself, it will attract the attention of your boyfriend. After a long time, you will find that your little romance has gradually affected your boyfriend. Second, you should take the initiative to choose some romantic occasions to date. For example, you can go to the movies together, play catch games together, and do something of mutual interest. After a long time, your feelings will gradually deepen, and he will feel your love while you love him, so he will change for this. Thirdly, if your own boyfriend is a very plain person, I think communication is the best solution at this time. Although he doesn't understand, you can just say, communicate with each other and give him some of your own ideas. Don't say that. This long time will only deepen the contradiction between you.
Generally speaking, I think the romance before a couple is not limited to some small surprises from the other side, it is just an additive to your feelings, so I think the essence of romance lies in whether your boyfriend loves you enough and treats you sincerely. If he loves you, his romance exists in every bit of you.
