They’re both toxic; Jimmy needed to stop lying to Fiona, even about small things and Fiona needed to communicate with Jimmy instead of just doing everything and assuming he’ll be ok with it. When Jimmy said Fiona made the decision to apply for guardianship of the kids without discussing it with him, that was a big one. I mean, she doesn’t need his permission but the least she could have done is say to him ‘look, I need to apply for guardianship, there really is no other way for my family to stay together. I know this will be a lot for you, but I’d really appreciate it you would stay and be there for me.’ The way she did things was all ‘I’m doing this, deal with it’.
Don't know any of them cuz I've never seen this before maybe bits and pieces on social media but maybe know a few of them from other movies or something
