She apparently loves me best, doesn't want to spend time with him or be nice to him.
She's not nice to him. He's tried to talk with her about it, He's tried changing his behaviour around her, to no avail.
Normal birth situation, he found the new born stage tricky.. actually he's found every stage tricky.. although he's also enjoyed lots of parenting stuff. He's not overly strict or odd with her, she just apparently prefers women and men other than her dad.
What can we do about it?
