What happens when your partner doesn't see the value in you and continuously hurts you by searching for something in others knowing it hurts you?

There is another scenario:

If my “partner” didn’t see value in me and hurt me searching for something in others, I would remind myself that I cannot change people, “make them see” or “make them love me”.

I would work hard at only being interested in people who are equally interested in me.

Why does everyone hate Anthony Joshua so much? I get that he isn’t the best heavyweight boxer ever but people claim he’s a no skill fighter but he has an Olympic gold medal, a world championship, and beat Klitschko, a dominant force in boxing

“Making someone love me” is the most painful, most fruitless of efforts, because love cannot be manufactured in this way.

I would leave this partner to grant him full freedom to go find whatever he is looking for and spend the time and energy that I put into that relationship getting to know myself. What I would find is someone flawed and worthy of love.

What happens?

If James Bond is meant to be the best secret agent in the world, how come all the bad guys in the World seem to know who he is?

I would realize that it’s not my partner who is hurting me. I am hurting myself, by agreeing to stay with someone who is looking for something he is not finding in me.

In one scenario, I stay with this partner, wonder why he doesn’t love me, and begin living in a world of my creation where I believe that, unfortunately, I am not worth loving.

I would ask myself why I consider it worth my time to be with someone who does not find me valuable. Identifying this answer will over time protect me from finding myself in this same predicament over and over.

Do people of NYC drive around Central Park all the time? Is there any subway tunnel to cross the park quickly? Is it annoying for people and does it cause traffic?

I believe this non-love is the best I can do and spend all my time and energy attempting to preserve the very thing that causes me pain.
