Yea I have a buddy who's a divorce lawyer and while I wanted to at first say 'this is clearly a troll' then I asked him about it and he was all 'yea no that sounds legit, the world is a trash fire and I pray for death' and then he unhinged his jaw and just screamed for twenty minutes.
Ok maybe that last couple bits was exaggerated, but yea according to him while obviously the internet is a throne of lies, even if he was trolling that dude totally syncs up with other very real shitbags that pull shit like that. Apparently 'if I file for custody first I win right' is like, a super common idea people have.
