I think it’s mostly due to her being the world’s biggest hypocrite. She acts all high and mighty toward John, treating him like crap throughout the whole story. John throughout the first part of RDR2 is literally trying to find his purpose in life and how to be a better man for his kid and future wife. Abigail sees none of that, she only sees what John has already previously done to them. Abigail herself however DOESNT CHANGE AT ALL. She wants everyone to change for her but she doesn’t want to change. She’s still the same dumb lady who was an illiterate prostitute that had a baby with a gang member. And now she’s trying to treat John as if he’s all wrong. Hypocrite

A decent portion of the community simply just hates women.

@Dildoguy - oohhhh thx yeah I thought it was just people hated her due to getting a bad impression from rdr1 with the whole attention wanting type personality and Old Friends, New Problems

@H. Roosevelt - haha yeah I keep seeing a bunch of kids who think they're so sigma commenting some deep ahh comment on a video showing how Abigail gets angry when John leaves pronghorn or gets a wanted level. something along the lines of "oh yeah women always play the victim and try blame you when you're at your lowest."

Because she doesn't realize that she's married to a videogame protagonist, and the people playing that protagonist just wanna run around and do cool outlaw stuff. For some weird reason, she seems to not want her husband to keep doing things that could get him murdered, arrested and put away for life, or hung, leaving her on her own, trying to raise and support her son in an era when there wasn't a lot of opportunities for women.

I guess she's just selfish. (/s)
