We focus so much on loving our partner but we cannot love our partner because we do not love ourselves!
Therefore, you cannot love someone in a relationship if you have not learned to love yourself!

We live with low self-esteem, without self-confidence, we have not been enough ourselves to love ourselves.

And the first thing we do in a relationship, we start to emphasize all the shortcomings of our partner.

Because we have not learned to love ourselves.
If we have not coped with this while we are single, then we drag it all into marriage, trying to correct our shortcomings in another person.
We put our expectations on another exhausted person.

And you are constantly angry because you do not feel cool enough, you feel your inferiority.

A partner cannot fill the emptiness and darkness that you have not dealt with.
