@HareThat happened to my cousin in the custody battle for his child whom he dearly loves. His wife was a complete bitch about the entire matter, demanding full custody, and got it...cause she's the mother, and isn't letting him see his child. He's doing his best to fight back to keep his relationship with his son alive, but with full custody, there's not a lot to be done.
I feel fortunate my parents had a relatively amicable divorce, and despite that my mother also got full custody, she at least realized I still needed my father in my life, and just because
she didn't love him anymore, didn't mean that
I shouldn't see him. Sadly, I think that's not necessarily the norm, as, let's be honest, women kinda tend to be spiteful (unlike guys who just punch each other and then everything's ok, women hold a grudge forever), and I've seen other split family's where the mother uses the children to hurt to divorced husband (it was truly awful, the mother was a drug addict had committed petty crimes, didn't show up to court and STILL got full custody). The law system is definitely rigged against men for family court, I've seen it all too much.
