He's telling you that you both need to be independent, and that he is moving that direction and his attention is going to shift to his child. That's mature of him, so take heart that he wants to be a good dad and provider for his family. While that can also hurt, of course we know that we just raise children, then let them go live their life freely. It isn't fair or healthy to be dependent on our children financially or otherwise.

to you for your hurting and disappointment.

Congratulations on upcoming birth of your grandchild !
