She really does herself no favour with Aaron. Yes he has issues and his outbursts are terrible but everyone of them seems to triggered by something she has done, almost intentionally get this exact reaction from him. He's obviously in control of his own emotions and actions but she's by no means an innocent bystander. It seems as soon as he tries to get himself back on the straight and narrow it doesn't fit her narrative and next thing you know he's mouthing off about guys that she's been with, and how would be even know that unless she somehow makes sure he find out. She knows exactly how to push his buttons.
I really think he needs to speak to someone professionally to held him detach from her completely and not react to her, it's the only way he'll be able to move forward and be a good dad to his kids, because he does have the capability but for some reason she still seems to have control over him.
But then I read that back and I don't want to defend him, he's a grown man, but yeah there are definitely trigger points to his behaviour that only he can change. Mind you I think Talia would push anyone to the brink the way she carries on.
