Women need more attention than men, you need to know that. For women, attention is always important. There is a feeling of being appreciated when someone is paying attention to us, and how happy it is when someone else can understand us without being asked. You yourself have said, that love also needs to be maintained. So as not to be boring, so as not to be just like that.
And all men should understand; In order to obtain and maintain a woman's love, all a man has to do is give sufficient, genuine care. Unfortunately, not all men do that. Even against his own partner.
