Maybe if I had done more, he would have reach out to HER more.
Nope. This is on him. He wasn’t sufficiently interested in being a parent to reach out more to her. Let him show you what kind of parent he’s going to be now. It’s not your job to manage his relationship with her. If he’s going to be a rotten parent you can’t fix that. And frankly, if he’s going to be a rotten parent, maybe it’s better your daughter doesn’t get more attached.
