We list the stages of love, if we are talking specifically about the relationship between a man and a woman:

Love of partners, mutual sympathy.
Saturation, as in food - I really ate already; in other words, banal addiction.
Disgust is an unpleasant feeling, no one plans to experience it, but without it, true love, unfortunately, is impossible.
Humility is the understanding that you still need to live together, you will have to endure each other all your life, however, at this stage, a loving person learns to extract practical benefits from the current situation.
Study is the discovery of previously unknown qualities in a partner.
Friendship - at this stage, loving hearts experience a strong emotional closeness, which is more characteristic of friendship.
Doubt - maybe I'm still wrong, and the choice of my whole life was not really intended for me.
Passion - understanding with age that passionate relationships are possible not only in the physical plane. Strong passion and attraction arises against the background of strong emotional closeness of partners. In simple words, it is necessary to learn to love not only with the body, but also with the heart and mind.
Love - that's it! Understanding comes when it is often too late. And it is at such moments that you can’t understand why I couldn’t come to this before, and it’s not clear what was in the way. And it interfered with the lack of wisdom, which is so necessary for women; and lack of action, and correct conclusions, which is so characteristic of men.
Time - time has no power over holy love. And nothing can separate loving hearts.
The state — everything is the energy of Love, and the Universe strives to pass into the state of this feeling.
Love is like the dependence of two hearts. If lovers love each other very much, and at the same time cannot be together due to any prevailing reasons, this situation can bring both unbearable pain and a desire to get closer at least for a few moments in order to feel the native breath nearby and the desired touch at arm's length .
