After a painful breakup, protecting oneself is understandable. But avoiding every possibility of closeness can also prevent meaningful relationships from developing.
The goal is not to become unreachable.
It is to learn that
closeness and self-respect can exist together.
A healthy relationship should allow both people to have individual interests, friendships, personal space, and the freedom to express disagreement without fear.

11. Her Desire for Intimacy May Change, but It Does Not Necessarily Disappear
One common assumption is that a woman who lives without a man for years eventually stops wanting physical intimacy, affection, or romantic connection.
That is not true for everyone.
Human desire varies widely. Some women experience a strong desire for romantic or sexual intimacy throughout their lives. Others experience it less frequently, and some feel little or no interest in sexual relationships.
These differences can reflect personal preference, health, hormonal changes, medication effects, emotional experiences, cultural background, and many other factors.
