He can't claim that he "left" for the benefit of his kids when he was begging Nick's live-in coke whore to take him back as his wife again.
Bullshit. He absolutely can. Because it was his wife.
Did he intend to let her keep doing coke in the house?
Look bro, I know you absolutely hate the guy, for whatever reason, but as I said before, when you are actually in love with somebody, you will actually put in some goddamned effort to fix a shitty situation and reestablish a healthy relationship. At least to a point.
I do not see any problem with him extracting himself (and his kids) from that situation, and then making one last good faith effort,
from a distance, to extricate his actual fucking wife. Who knows what his plan was. You assume that he was just gonna keep letting her do coke in his home. Maybe if he got her back, he would get her into detox. I don't know.
Indeed, I would argue if he simply just walked away, without doing
anything further to save his marriage from the Balldo scourge, he would be a bigger failure of a man, and a bigger cuck.
Now, if Aaron were to take her back
now, I would ridicule the shit out of him, but he doesn't seem to want her back, and the divorce went through. So it's over and done with. She is well and truly lost to the Balldo and drugs at this point. May God have mercy on her soul.
