Any relationship between two people always develops individually, and only the two of them know what actually connects them. No matter how strong the love of a man and a woman, most often one of them still loves more than the other.
When a person realizes that he loves a partner more and more deeply than they love him, it is his personal choice - whether to continue such relationships and how much to give love and warmth. However, if a person understands that they love him more than he does, this is already a certain responsibility for the feelings of another.
Stronger or just different?
Each person loves in his own way. Sometimes the concept of "loves more" is not entirely objective. A man, for example, can love a woman as much as he can express this feeling, but it will still not be the same as the mutual feeling of a woman. And most often the power of love is manifested only in what one person does for another.
Therefore, if a person understands that they love him more than he does, he should reconsider the ways of expressing his love. Perhaps he can do something for another person that he has not done before, or say about his feelings. Very many people do not know how to express their love in words, then to show the depth of their feelings, you can do this by some kind of action.
You can review the romantic films that girls like. The principle of all such films is almost the same. A man conquers a woman with the help of feelings and a special approach to current situations. It is for non-standard male behavior that women like to watch such films and secretly "try on" the role of the main character.
