I don't agree that men are always the biggest losers. I have friends who are women who have fared so much worse than their male partners for a variety of reasons. I do believe though that (at least in my bubble of the world) it's generally thought that men are the winners, so when you're the loser, it's fairly isolating and lacking of any sympathy or concern in a situation that can be absolutely crushing. If you want support, you're likely not going to get it unless you have close family or friends who care enough to see past unfortunate social norms and simply care about you.

If you involve kids, I think it gets quite a bit worse here. My experience has been that family law is mostly a level playing field, but mothers still have the upper hand. This again is something which no one really cares about or will do anything about; you have to suck it up and carry on. There is no way around it.
