There should clearly be a photo of the plinth, because during the divorce proceedings, the self-esteem of most people (especially women) tends to the plinth)
Now imagine that when love arose between a man and a woman, he madly admired her, believed in her capabilities and success, talked about how beautiful her body is and how delicious her food is .. And the woman's self-esteem certainly improved. She wanted to believe her beloved, because he sees her real, so beautiful. And a man becomes for a woman a kind of reference point for her self-esteem.
Therefore, the sharp statements of a loved one during quarrels are so painful ...
Now imagine that the couple decided to divorce. And now there is no man next to him who will remind a woman that she is beautiful. And most likely, the same man will say everything exactly the opposite, in order to hurt his ex-wife more painfully.
I described the situation using the example of a woman. But a man could feel the same way.
What to do with self-esteem in divorce? Looking for another person who will admire you? This is unlikely to be effective ...
I would suggest changing the landmarks. Do not rely on the opinion of external actors ( other people), but pay attention to internal resources (i.e., yourself).
We don't see much in ourselves.
