Happy for you, bro that's huge! I remember when I was fighting tooth and nail for ful custody of my daughter; the battle was worth it. I've had full custody for eight years now, and trust me, bro, there’ll still be tough moments bullying at school, a broken heart, puberty being an absolute mess, you name it. But you’ve got this. Yeah, there will be times you doubt yourself; that's normal. Every good dad doubts himself at some point, so you’re fine.
