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?

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.

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

There is another scenario:

Why can't NASA just bite the bullet and launch a plainly simple mission, audited by flat earther peers start to finish that definitively proves to even the smallest minds that the earth is an oblong spheroid, and not flat?

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

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.

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.

There is any scientific evidence that we live in a sphere. Why do others say that we lives in a flat Earth but there is no evidence that they have proven the existence of a flat earth?

What happens?

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.

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”.

How will Israelis respond to someone claiming that anti-Zionism is not anti-Semitism, in the same way as anti-feminism not being misogyny and opposing same-sex marriage not being homophobia?

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.
