Should I let him go so he can go have babies with someone else? Should I just suck it up and have a baby? Why can’t I just want this?

Should I let him go so he can go have babies with someone else? Should I just suck it up and have a baby? Why can’t I just want this?
I feel like I broke this piece of our relationship and I want so badly to fix it, but he won’t meet me there.
I want to have a healthy family that’s able to have a conversation about things we don’t necessarily agree on without it becoming heated and hurtful. How do we get out of this mess?
Am I broken for not wanting to go back?
I love this human being so much, but I can’t deal.
I’ve heard some of them call me manipulative or judgmental, but I was really just trying to get them to snap out of it.
My question is – is someone like that really able to change?
I really like her, but I don’t know how to approach this.
It’s so difficult to watch someone you care about shrink away and isolate themselves, not fully understanding what’s happening.
I don’t want to quit prematurely, but I don’t know how much longer I can do this.
I don’t want to argue, or fight, or pretend things are okay when they’re not. I want out.
I thought I enjoyed helping people, but now I’m concerned that I was only doing this out of my own codependency and that all of my efforts were really self-serving in the long run.
