Give her a sense of security and reassure her that in life, you may see many lovers quarreling because of other opposite sex. One reason is to care too much about each other, and the other reason is insecurity. This man cannot make them feel comfortable. Safety is what many women want. No one likes the feeling of being dominated by gains and losses. If you like someone, you want her to put all her attention on you. Therefore, men should grasp the distance between themselves and the opposite sex around them and give their girlfriends more sense of security, so that they can feel at ease and be happy.
Give her romance and make her feel happy. No matter what age, women are more or less vain. They want their men to be romantic, which can satisfy their vanity and make her happy with you. Two good friends are chatting together. At Christmas, a woman and her boyfriend bought her a present, while another woman and her boyfriend gave her nothing. This contrast shows that one of the women and men is not romantic at all. In the long run, this woman will be more dissatisfied with her and will not love her very much.
Women are not as complicated as you think. Men shouldn't spend too much time on games or work. They should spend some time learning more about their girlfriend and what she really wants. You may have spent a lot of time at first, but the farther you go, the more you will find that the woman who gave you everything saw it and remembered it. She will give you something in return and will like you more and more. So I think that grasping these "key points" of women will make the other person love you deeply, which is purely personal.
