Love is divided into the following stages:

The first stage of ignorance:

I don't understand the meaning of love, and I don't understand what feelings are. Is the behavior orientation based on inner curiosity or rebellion against teachers and parents?

The second stage vanity period:

This is an extension of the ignorance period. I don't know the meaning of love, and I don't know what feelings are. Behavior orientation is based on inner curiosity or rebellion against teachers and parents, or desire for sex.

The third stage of ignorance:

At this stage, there has been a need for love or affection, or a sense of security, or an ATM, or loneliness, or physical needs, and most of them don't know it.
